Abstract：PID control as a common control strategy has been widely used in practical control systems. The reality of the control system will encounter the saturation problem of the actuator. Integral action of the PID controller will cause the system to enter the saturated zone which can not get rid of it in time, resulting in deterioration of the system control performance. Many scholars have proposed various methods to solve the problem of PID Anti-windup. In this paper, six methods which include the state observer approach, the conditioning technique, the incremental algorithm, the Anti-saturation of integral algorithm, the conditional integration method and the variable-structure of Anti-windup have been simulated and compared to show that the conditioning technique has a better Anti-windup effect.
