Modeling and Passivity-Based Control of the Pierburg mechatronic actuator

Abstract

In this paper, we present an overall study focused on 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 obtained model from the identification procedure is sufficiently closer to the practical actuator behavior and captures most of its characteristics. This mechatronic actuator is subject of parameter variation during its life span. A nonlinear control based on the Interconnection and Damping Assignment Passivity-Base Control (IDA-PBC) is designed in order to ensure the desired performances. Simulation results show the efficiency of both the obtained model and the control strategy.
