Study on the Double Closed Loop DC Motor Speed Control System Based on Parameter Self-tuning by Fuzzy Control

According to the mathematical model of a DC motor, a transfer function model of the DC motor is established by analyzing DC motor speed control principle. according to the parameters of the fuzzy control algorithm of self-tuning function and robustness properties of the algorithm, a double loop DC speed control system is established. The fuzzy controller is designed by using fuzzy toolbox, the fuzzy param-eter self-tuning PID controller is established by combining it with traditional PID controller, through Matlab/Simulink simulation software, test results show that, the fuzzy parameter self-tuning PID control strategy can accelerate the response speed of motor speed control system, has the advantages of good stability, high precision, strong robustness, and obtained the good control effect, has higher application value.
