Design and Fuzzy Adaptive PID Control of High Power DC Motor Colsed -Loop Conruol System

摘要：

The paper designs a high power DC motor closed loop control system, mainly including design of H bridge drive circuit, the one of speed detection circuit and Signal conditioning circuit On this basis, in order to improve the performance of motor running, it proposes a fuzzy adaptive PID control algorithm. Firstly, one determines the degree of membership of the input values to defined fuzzy sets, then constructs the fuzzy rule table according to experience and experiments, finally, makes defuzzification for every parameter of PID controller, that is, Kp, Ki, Kd. Experiments show that both hardware implement and software control algorithms are reliable, the running performance of the system is robust before or after adding load.
