A Cascade PID-PD Controller for a Hybrid Piezo-Hydraulic Actuator in Camless Internal Combustion Engines
Activity: Talk or presentation › Conference Presentations › Research
Paolo Mercorelli - Speaker
This paper deals with a hybrid actuator composed by a piezo and a hydraulic part
and with a cascade PID-PD control structure for camless engine motor applications. The idea is to use the advantages of both, the high precision of the piezo and the force of the hydraulic part. In fact, piezoelectric actuators (PEAs) are commonly used for precision positionings, despite PEAs present nonlinearities, such as hysteresis, saturations, and creep. In the control problem
such nonlinearities must be taken into account. In this paper the Preisach dynamic model with the above mentioned nonlinearities is considered together with a cascade PID-PD controller which is realized through sliding surfaces. Simulations with real data are shown.
