NMPC-Based Trajectory Tracking Control of a Piezoelectric Ceramic Actuator Using the Bouc–Wen Model

Piezoelectric ceramic actuators provide high-resolution motion but exhibit path-dependent hysteresis and mechanical dynamics that degrade trajectory tracking, particularly under time-varying commands. This paper develops a nonlinear model predictive control (NMPC) method based on a standard Bouc-Wen hysteresis model co...
