Abstract:

Article Preview

Piezoelectric actuator is being widely used in vibration suppression and micro positioning applications for fast response, nanometer resolution, no backlash, no friction and bigger driving force. However, its inherent hysteresis characteristics between the input voltage and output displacement limit its control accuracy. An efficient way to eliminate this limitation is to model and control this hysteresis. In order solve the problem, the characteristic of piezoelectric actuator was introduced, and its static hysteresis was studied by experiment. A Preisach model was put forward to describe the hysteresis nonlinearity; a model feedforword controller was used to quicken system response. Control experiment results indicate that the proposed model and control method has good performance for precision control
