An Adaptive Resonance Regulator for an Actuator using Periodic Signals in Camless Engine Systems

Research output: Journal contributionsConference article in journalResearchpeer-review


The 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 consists of 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. The resonance controller guarantees that the hydraulic part of the actuator works at the frequency given by the velocity of the revolution of the engine. The parameters of the controllers change adaptively in accordance with the change of the velocity of the revolution of the engine. Simulations on the valves of a camless engine are shown. © 2016
