Description
Summary:This paper deals with an adaptive control strategy based on the resonance concept to minimize the regulation energy of a new generation of actuators for intake valves of camless engines. The new actuator contains different parts, but basically it consists of a piezo part and a hydraulic one. Even though this work considers a particular application, the solutions proposed in the paper are quite general. The regulator consists of a cascade structure which combines feedforward actions with an external resonance controller strategy. These controllers guarantee that each single part of the actuator works at the frequency given by the velocity of the revolution of the engine. The parameters of the valve controller and of its feedforward action change adaptively in accordance with any change in the velocity of the revolution of the engine. Real measurements on an intake valve of a camless engine are shown.
