It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0022] like Figure 1 As shown, the present invention provides a dynamic control method for a battery electrode infrared-hot air combined drying equipment, specifically including the following steps: include: Step S100: Collect multidimensional characteristic parameters of the drying process, and establish an ideal drying process model for the battery electrode based on the multidimensional characteristic parameters. The multidimensional characteristic parameters include at least the electrode moisture content, temperature, and ambient temperature and humidity parameters.
[0023] Specifically, multidimensional characteristic parameters of the drying process are collected through sensors and data acquisition cards, including but not limited to: solvent partial pressure on the upper surface of the electrode (collected by a pressure sensor), temperature of the upper surface of the electrode (collected by a temperature sensor), temperature of the lower surface of the electrode (collected by a temperature sensor on the roller surface), ambient temperature (collected by a temperature sensor), ambient humidity (collected by a wet-bulb and dry-bulb hygrometer), radiation intensity of the infrared lamp (collected by a radiation intensity sensor), and moisture content of the electrode (collected by an online quality measurement system). The collected multidimensional characteristic parameters are filtered, denoised, and normalized to ensure data accuracy and consistency. Based on the collected multidimensional characteristic parameters, a multidimensional parameter model of the ideal drying process is established using mathematical modeling methods (such as system identification and machine learning) to describe the dynamic characteristics of the multidimensional parameters changing with moisture content during the ideal drying process. For example, the system identification method models the system using input and output data to obtain the dynamic characteristics of the multidimensional parameters changing with moisture content. Machine learning methods use algorithms such as neural networks or support vector machines (SVM) to train the model based on historical data and predict the dynamic characteristics of the multidimensional parameters changing with moisture content. The moisture content is calculated as follows: (1) In the formula, It represents the ratio of the free moisture content to be removed at a certain moment to the initial total free moisture content; , and Let represent the initial, equilibrium, and arbitrary drying time t of the electrode, respectively, in g / g. The moisture content of the electrode after drying is... much smaller and And since it is approximately 0, it can be simplified to .
[0024] Step S200: Simulate and control the ideal drying process model to obtain simulation control records.
[0025] Specifically, simulation software (such as MATLAB / Simulink, ANSYS Maxwell, etc.) is used to simulate the established multi-dimensional parameter model of the ideal drying process. In the simulation environment, drying parameters corresponding to different electrode moisture contents, such as infrared radiation power, hot air temperature, and hot air velocity, are obtained, and control algorithms are implemented, for example: PID control, using proportional and integral controllers to adjust infrared radiation power, hot air temperature, and hot air velocity. An improved cosine delay feedback control (ICDFC) is used, utilizing the difference between the output of the controlled system and its own delay of one cycle as the feedback quantity. After passing through a cosine function and feedback control parameters, the control signal is obtained. Input and output data during the simulation process are recorded, including electrode moisture content, temperature, ambient temperature and humidity, infrared radiation power, hot air temperature, and hot air velocity.
[0026] Step S300: Based on the predetermined extracted electrode moisture content, extract the simulation information from the simulation control record to obtain the simulation output quantity.
[0027] Specifically, the predetermined extraction of electrode moisture content is a pre-set interval for extracting data from the simulation control record, for example, extracting data once every 1% change in moisture content. Simulation information from the output terminal is extracted from the simulation control record at the predetermined extraction frequency. The extracted data includes temperature signals, ambient temperature and humidity signals, infrared radiation power values, hot air temperature values, and hot air velocity values. The extracted simulation outputs are stored in a database or file for subsequent processing.
[0028] Step S400: Compare the simulated output with the real-time characteristic parameters collected during the actual drying process to obtain the multidimensional characteristic parameter comparison deviation of the target moisture content range, wherein the target moisture content range and the actual collected moisture content range of the multidimensional characteristic parameters have a corresponding relationship.
[0029] Specifically, the target moisture content range of the simulation output is determined based on the moisture content of the electrode collected during the actual drying process, and the multidimensional feature parameters (first output) of the collected actual drying process and the multidimensional feature parameters (second output) corresponding to the target moisture content range are compared.
[0030] In one possible implementation, before comparing the first and second output values for the corresponding moisture content range, step S400 further includes step S410, acquiring the parameter record of the adjacent previous drying cycle of the actual drying process. This is denoted as the preceding parameter.
[0031] In step S420, within the same moisture content range, the preceding parameters and the multidimensional characteristic parameters (second output) of the ideal drying process provide a clear calculation benchmark for the deviation calculation of the multidimensional characteristic parameters (first output) of the actual drying process corresponding to the multidimensional characteristic parameters (second output) within the target moisture content range. By comparing with the preceding parameters, the dynamic control system can better understand the current trend of change, thereby adjusting the dynamic control strategy to adapt to the changes in the drying process.
[0032] In one possible implementation, step S400 further includes S430, which involves sequentially sampling the first output and the second output based on the electrode moisture content according to the uniform sampling principle, to obtain a first sample set and a second sample set, respectively. Uniform sampling refers to collecting data within a fixed electrode moisture content interval to ensure that the sampling points are uniformly distributed along the electrode moisture content axis.
[0033] Step S430: Based on the interval of electrode moisture content range, obtain the comparison deviation between the first sample set and the second sample set.
[0034] Step S500: Based on the comparison deviation, dynamically control the infrared heating power, hot air temperature, and hot air speed in the target time zone.
[0035] Specifically, new control signals are generated based on the target deviation. For example, the parameters of the PID controller and the feedback control parameters of the ICDFC control strategy are adjusted according to the deviation to reduce it. The generated control signals are then sent to the control unit of the dynamic control system for dynamic adjustment. For instance, by monitoring multi-dimensional characteristic parameters of the actual drying process in real time, the control signals are dynamically adjusted to ensure that the target deviation is controlled within the expected range. For example, the output of the dynamic control system is monitored every 1% moisture content, and the control signals are adjusted based on the real-time multi-dimensional drying characteristics.
[0036] This application employs a method of collecting multi-dimensional feature parameters to establish an ideal drying process model, extracting simulation output based on simulation control records and comparing and analyzing the target comparison deviation, and then performing dynamic control based on the electrode moisture content. This solves the problem that existing electrode drying processes with fixed parameters cannot adapt to complex and variable working conditions, resulting in high energy consumption and unstable electrode quality. This effectively improves drying uniformity and energy utilization, and ensures stable electrode quality.

[0048] The present invention discloses a dynamic control method for a battery electrode infrared-hot air combined drying equipment, the working principle of which is as follows: The device mainly consists of an infrared heating component, a hot air circulation component, a conveying mechanism, a temperature sensor group, a solvent partial pressure sensor group, a data acquisition module, and a central control unit.
[0049] During the electrode drying process, the electrode is continuously conveyed into the drying chamber by the conveying mechanism. The infrared heating component radiates heat to the surface of the electrode, while the hot air circulation component provides hot air from the bottom or side wall to achieve convective heat transfer, so that the moisture and solvent inside the electrode migrate from the inside to the outside and are carried away by the airflow.
[0050] Temperature sensors are positioned on the surface, bottom, and environment of the electrode to monitor the temperature distribution of the electrode in real time; solvent partial pressure sensors are used to detect the solvent vapor concentration in the drying chamber. The central control unit first establishes an ideal drying process model based on ideal drying process data of electrodes with the same formulation, and obtains the temperature field, moisture content, and solvent partial pressure change curves under ideal conditions through simulation.
[0051] In actual drying operation, the control unit receives sensor feedback signals in real time and compares its real-time characteristic parameters with the simulation output of the ideal drying model to calculate the target parameter deviation. Based on the magnitude and trend of the deviation, the system automatically adjusts the infrared heating power, hot air temperature, and hot air velocity to achieve closed-loop dynamic control. When the deviation is within the allowable range, the system maintains the current control parameters; when the deviation exceeds the predetermined threshold, the system performs adaptive adjustment to restore the ideal drying trajectory.
[0052] Through the above methods, the present invention achieves dynamic and intelligent control of the infrared-hot air combined drying process, which can effectively reduce uneven electrode temperature and local over-drying, improve drying rate and energy utilization efficiency, and ensure the consistency of electrode moisture content distribution and microstructure stability.
