N2 - This paper describes a method for controlling a piezoelectric stack actuator with hysteresis nonlinearity. The actuator used is a high-performance monolithic multilayer piezo actuator. The proposed control method involves a circuit, which was built with a capacitor in series with the piezo actuator to provide a measured output voltage which is proportional to the charge on the piezo actuator.The controller is designed based on a model of the hysteresis nonlinearity constructed using experimental data. The paper considers a robust H infinity tracking controller to control the piezoelectric actuator. The controller is designed using an uncertain system model. Simulation results show that the controller can significantly reduce the effect of the hysteresis nonlinearity.
