音圈电机全局自适应非奇异快速终端滑模控制
Voice Coil Motor Global Adaptive Non-Singular Fast Terminal Sliding Mode Control
摘要
Abstract
In order to improve the dynamic performance of the voice coil motor drive system,a global adaptive non-singular fast terminal sliding mode control strategy was proposed.On the basis of the non-singular fast terminal sliding mode controller,a global sliding factor was introduced to improve the transient response of the system;meanwhile,adaptive control and non-singular fast terminal sliding mode control were combined,and adaptive control could be utilized to automatically adjust the parameters according to the real-time state of the system and the external disturbances,to reduce the perturbation,and to improve the system′s robustness and immunity to disturbances.Finally,the vibration was weakened by using changing the sign function in the control law to a kind of saturation function of the boundary layer;the stability of the proposed controller was proved by the Lyapunov stability method.Finally,the global adaptive non-singular fast terminal sliding mode control was simulated and compared with proportional integral derivative control(PID)and sliding mode control(SMC).The results show that the proposed global adaptive non-singular fast terminal sliding mode control improves the response speed and control accuracy of the dynamic system,and effectively improves the dynamic performance of the system compared with the PID control and sliding mode control.关键词
