Design of a multivariable controller for an engine eddy dynamometer system

The ever increasing demand for reducing fuel consumption and emission has driven the improvement and innovation of new technology in an engine and an engine dynamometer system for an engine testing equipment. This paper presents a novel control method of the engine eddy dynamometer system for the automobile engine tester, an engine eddy dynamometer measurement and control system is developed based on Embedded PC and NI (National Instrument) real-time module by Labview software. Aiming at a multiple-input-multiple-output engine-dynamometer complex system,a multi-loop optimized subdivision PID controller of engine eddy dynamometer is designed. The experimental results indicated that the controller owns excellent performance and adaptability.
