Modeling and backstepping-based control of an electromechanical actuator

Abstract

This paper deals with the modeling, identification and control of the Pierburg mechatronic actuator. This actuator is used in the BMW M57 diesel engine to control all the air which are charged and entered in the vehicle engine. The actuator static characteristics are exploited to model the system dynamics. Then, the obtained model from the identification procedure is used to design a nonlinear control based on the backstepping and Lyapunov theory. Simulation and experimental results are presented.
