Piezoelectric actuator has been frequently utilized in the micromanipulation control. However, the rate-dependent hysteresis properties in the actuator affect severely the high precision tracking control. In this study, a Hammerstein-based model with Bouc-Wen hysteresis nonlinearity is proposed to describe the dynamic characteristics of rate-dependent hysteresis in a piezoelectric actuator. The Bouc-Wen...
Most smart materials used in engineering applications have rate-dependent hysteresis nonlinearity. In this paper, a Hammerstein-based model is proposed to describe the dynamic characteristics of rate-dependent hysteresis in piezoelectric actuator. A Bouc-Wen model is used to approximate the static nonlinear characteristic while a linear dynamic model is constructed to capture the rate-dependent property...
