Abstract:
In view of the appearance of nonlinearity and time variation of parameters in the control system for guided projectiles,it is difficult to acquire a satisfactory control effect only using the conventional PID. According to the definition and properties of fractional calculus,the structure of fractional order controller is constructed and the effect of controller parameters on the system performance is analyzed. The fractional order controller is applied to the control system design for guided projectiles and the fractional order control system is also investigated. The results show that the fractional order controller has stronger robustness and anti-interference ability than the conventional PID controller. It can be applied to the control system of guided projectiles. The fractional order controller has better response characteristics than the conventional ones in both frequency and time domain. The results presented here are useful for the application of the fractional order controller to the control system of guided projectiles.
