Problems solved by technology

At present, the parameter tuning of the PID controller is often performed manually based on the characteristics of the controlled object’s transfer function and based on experience. The parameter tuning method is complicated and requires a lot of time and energy. The best performance of the controller, resulting in low control precision of the PID controller, and the effect of the PID control system is not good

Abstract

The invention relates to the field of PID control system design, in particular to a PID controller parameter setting method and device, a storage medium, a terminal and a system. The method comprises:obtaining input and output sampling data of a PID control system, and calculating the control error of a PID controller according to the sampling data; if the control error exceeds a preset thresholdvalue, obtaining output data of a PID controller, and sending the output data of the PID controller to a neural network model to obtain identification output data; and sending the identification output data to a single neuron controller, controlling the single neuron controller to adjust parameters of a neural network model according to the identification output data to obtain an adjusted neuralnetwork model, and determining parameters of a PID controller according to the adjusted neural network model. According to the invention, the parameter setting efficiency of the PID controller can beimproved.

Description

technical field [0001] The present application relates to the field of PID control system design, in particular to a parameter setting method, device, storage medium, terminal and system of a PID controller. Background technique [0002] In the industrial control process, the PID controller is currently the most widely used controller. In the application of control methods such as motion control and process control, the application of the PID controller accounts for more than 90%. The parameter tuning of the PID controller is the core content of the control system design. It determines the proportional coefficient, integral time and differential time of the PID controller according to the characteristics of the controlled process. At present, the parameter tuning of the PID controller is often performed manually based on the characteristics of the controlled object’s transfer function and based on experience. The parameter tuning method is complicated and requires a lot of t...
