The control method comprises the following steps: obtaining matched heating parameters according to an input injection molded material to control the heating of a heating tube, slowly lowering a servo cylinder, and obtaining pressure detection values collected by pressure sensors; checking whether the pressure detection values pass the check; if not, controlling the servo cylinder to continue slowly lowering; if yes, updating the number of passes; if the number of passes is greater than a threshold, completing the correction process; if the number of passes is not greater than the threshold, controlling the servo cylinder to stop working and slowly lowering again after a preset interval.

According to the checking result, the lowering correction process of the servo cylinder is automatically adjusted, thereby realizing intelligent correction control of the injection molded part and greatly improving the correction efficiency of the injection molded part.

This invention discloses a control system for intelligent medical mobile devices, relating to the field of intelligent medical device control technology. The system includes a data acquisition module, a feature acquisition module, a dynamic model, an error compensator, and a torque synthesis module. The data acquisition module collects kinematic data such as the device's three-axis acceleration, three-axis angular velocity, and center-of-mass coordinates. The feature acquisition module collects biometric data such as the pulse wave, respiratory rate, and blood oxygen saturation of the patient being served. Both types of data are simultaneously injected into an embedded dynamic model with preset no-load and load coupling inertial parameters. An ideal torque vector is obtained through forward dynamic inference. A closed-loop error compensator compares torque differences to generate torque correction increments, which are then superimposed to form a corrective control command. This system can adapt to different load conditions of the device, reduce torque output deviation, and improve the accuracy and adaptability of device control.

The method includes: collecting multimodal time-series sensor data from manufacturing equipment to establish an execution-layer semantic benchmark library and a cognitive-layer confidence parameter set; selecting corresponding commands from three levels of control commands based on the confidence level and issuing them to the actuator; registering a semantic blind zone hypothesis when the confidence level is below a threshold and calculating the optimal detection action to superimpose and issue it to the actuator; and continuously issuing corrective control commands after updating the execution-layer semantic benchmark library using the detection residual vector. This application solves the problems of existing digital twin control systems being unable to recognize semantic mapping failures under operating condition drift and the virtual model being unable to actively apply directional detection to the physical actuator to eliminate cognitive blind zones.
