Abstract :
Today piezoelectric actuators are used in a growing number of applications. This article presents a new switching amplifier circuit for multilayer actuators, which allows a fast and precise driving as well as the recovery of energy from the actuator. Having modeled the power electronic analog circuit, its behavior could be well reproduced by a simulation. The design of a digital controller, which was considerably facilitated by this simulation, is presented. This controller and the analog switching amplifier as well as a model of the piezoelectric actuator are part of mixed analog digital simulation.
