在这份报纸,有不安评价(SMCPE ) 的滑动模式控制结合了一个反的磁滞现象赔偿者为与压电的使活动追踪一个 microposition 系统的控制的运动被建议。反的磁滞现象赔偿者被采用取消磁滞现象非线性,因此与一个倒置错误把非线性的系统归结为一个线性系统。然后,一个 SMCPE 控制器被采用处理所有 unmodeled 动力学和骚乱,瞄准改进动态性能和系统的坚韧性。一个压电的致动器的一个实验被介绍表明建议控制计划的可行性和有效性。结果证明为快率的控制输入,建议方法能够导致系统行为的好表演。
In this paper, a sliding mode control with perturbation estimation (SMCPE) coupled with an inverse hysteresis compensator is proposed for the motion tracking control of a microposition system with piezoelectric actuation. The inverse hysteresis compensator is employed to cancel the hysteresis nonlinearity, thus reducing the nonlinear system to. a linear system with an inversion error. Then, a SMCPE controller is adopted to deal with all the unmodeled dynamics and disturbances, aiming at improving the dynamic performance and the robustness of system. An experiment of a piezoelectric actuator is presented to demonstrate the feasibility and effectiveness of the proposed control scheme. The result shows that for a fast-rate control input, the proposed method is capable of leading to a good performance of system behavior.
