Active vibration control for large slenderness ratio missile based on PID controller

摘要：

　　Vibration is an important issue in many applications.This paper presents a new approach of proportional-integral-derivative (PID) controller tuning via an genetic algorithm that optimally suppresses the vibration of a large slenderness ratio missile using a piezoelectric actuator.In this paper, the motion equations of the flexible missile, which subjected to a thrust at its rear end, are derived based on Lagrangian approach.A PID controller is designed to suppress the inevitable vibration of the missile.Minimizing the root mean square displacement of transverse vibration,genetic algorithms is used to optimize the parameter of PID controller.The performance of PID controller is compared with without control, the PID controller is more effective than without control.It is feasible to reduce vibration and improve stability of flexible missile by means of PID controller.
