The paper describes the principle of fuzzy control, PID ( proportion - integral - derivate) control and adjusted PID control by fuzzy logic on -line. According to the character of the object system ,it also shows application of PID's( proportion- integral- derivate) fuzzy modulation on -line in the tracking system for optimization. At the same time, the optimized system is simulated via simulink in tracking target and anti -jamming, then the input curve, the output curve and PID's variable curve are also analyzed. The result shows sensitive tracking and robust anti - jamming in the system. In turn, the corresponding theoretic circuit is designed. Through the simulation the internal working principle of fuzzy PID is analyzed and a base of innovation in theory is constructed.
