초록
For the displacement control of piezoelectric actuator, this paper proposed a method of designing the control algorithm, and presents the dynamic modeling equations which represent the hysteretic behavior between input voltage and output displacement. For this process, the piezoelectric actuator is treated as second-order linear dynamic system then a classical PID controller is designed and used to regulate the output displacement control of the actuator. To evaluate the performance of the proposed method, numerical simulation results were presented
