Modeling and PI-Fuzzy logic controller of the Pierburg mechatronic actuator

This paper focuses on the modeling, identification and control of the Pierburg mechatronic actuator. This is an air inlet swirl actuator. It is used in the BMW 6 cylinder diesel engine to control the air amount entering in the piston chamber. Physical model, which accurately reproduces the real behavior of this actuator, is developed using its static characteristics. This mechatronic actuator is subject of parameter variation during its life span. Therefore, a Pi-Fuzzy logic controller is designed to ensure the desired performance. Simulation results using Simulink and experimental results using Labview with CompactRIO are presented. Results show that the Pi-Fuzzy logic controller is able to govern the system and to guarantee the desired performance.
