摘要：
Piezoelectric materials are widely used as sensors and actuators in many applications. They allow efficient digital control of mechanical systems, but suffer from nonlinearity and hysteresis. This chapter presents a new digital open-loop control of piezoelectric bender for real-time applications in domestic appliances, for which strong specifications are good accuracy and low cost. The control algorithm, implemented in a microcontroller, solves the problems of nonlinearity and hysteresis. The chapter presents experimental results of the prototype that has been realized in the Indesit Company laboratories for future applications on domestic appliances. © 2009 pringer Science+Business Media B.V.
