Nguyễn Ngọc Sơn, Cao Van Kien, Tran Minh Chinh
Abstract
In this paper, an event-triggered sliding mode control with hysteresis is proposed for motion tracking of the piezoelectric actuator (PEA) in the presence of uncertainties, disturbances, and nonlinearity hysteresis characteristics. First, the dynamic model with hysteresis characteristics of the piezoelectric actuator (PEA) is described by the Bouc-Wen model. Second, the design of event-triggered sliding mode control (ETSMC) with hysteresis for the PEA system is discussed and proves the stability using Lyapunov’s Law. Finally, The piezoelectric actuator PZS001 of THORLABS are used to validate the proposed controller. Simulation results show the effectiveness of the ETSMC approach.
