In this paper, the analysis and elaboration of the theory of fuzzy control based on the analysis of fuzzy PID control and PID control of the basic characteristics. For motor speed control system to create a model, first fuzzy input variables, and the establishment of the fuzzy rules of fuzzy controller, fuzzy reasoning and anti-fuzzy, and so on completion of a series of fuzzy controller design. Will be applied to fuzzy control of PID regulator, the fuzzy PID control systems constitute a regulation. Finally, through the MATLAB software and basic fuzzy PID algorithm PID algorithm simulation comparison, observed both in the steady-state characteristics of the dynamic characteristics and differences, Based on laboratory test results available to the conclusion, fuzzy PID algorithm and the basic PID algorithm, the system of small overshoot and fast response, shorter settling time and improve the system dynamic performance.
