This paper considers an aggregate actuator consisting of a piezo and a hydraulic part. Moreover a cascade PI-PID controllers is taken into account for its control in automotive applications. In the presented work the Preisach dynamic model is taken into consideration a long with a cascade PI-PID controllers. In particular, the hysteresis effect is considered and a model with a switching function is used also for the controller design. Simulations with real data are
able to be seen in this contribution.
