Sliding Mode Control Using linear extended state observer(LESO)and Hysteresis Compensator based on Bouc-Wen model in Sinusoidal Position Control of a Piezoelectric
In this paper,a sliding mode control using LESO coupled with an inverse hysteresis compensator is proposed for the motion tracking control of a microposition system with piezoelectric actuator(PEA).The inverse hysteresis compensator is involved in eliminating the hysteresis nonlinearity reducing the nonlinear system to a linear system.Then,a sliding mode controller combining with LESO is adopted to handle all the unmodeled dynamics and disturbances,with an intention of improving and enhancing the dynamic performance and the robustness of system.The feasibility of the proposed control scheme is verified by experiment of a PEA.The result shows that when faced with a fast-rate control input,the proposed method can also ensure the system a good performance.
