The traditional DC speed regulation can not overcome nonlinear factors and is hard to meet certain occasions control requirements of high precision and high performance puts forward, the DC motor speed control system based on fuzzy PID control . Introdues the theory and characteristics of fuzzy control, analyzes the control principle of the fuzzy PID controller, determines variables of fuzzy anguage and sub-ordinative functions, and stipulates the methods of fuzzy rules and inverse fuzzy. Finally, the modeling and simulation are made with Matlab/Simulink, the result shows that the DC motor speed control applying fuzzy PID control has better control precision and robustness than traditional methods，and it also improves dynamic and static performance of electrical motor.
