| Abstract: | In order to study the essence of the input-output of piezo-actuators, the electromechanical dynamic model of the piezo-actuator is presented, and the cause of formation of nonlinear hysteresis inhered in the actuator is explained based on the signal flow chart of the model, two dimension piezo-type microdisplacement platform and its activating power with charge feedback are developed for verifying the model and the explanations. The model analysis and experimental results show that effect of the exterior charge feedback loop in the power is similar to the interior charge feedback loop which is formed by the direct piezoelectricity of the piezo-actuator. |
