摘要： Piezo actuators play a key role in advanced technologies, such as biology, materials science, lithography, etc. However, the control for the piezo actuators is very complicated due to the existence of the hysteresis nonlinearity between the input and the output. When these actuators are applied to servo systems, the strong coupling between the hysteresis nonlinearity and the vibration dynamics of the systems will make the control problem of the servo system very challenging. In addition, both the hysteresis and the dynamics vary with the environmental and load conditions. This talk discusses the advanced control problems for the piezo-actuated positioners.
