Switched H-infinity control strategy of automotive active suspensions
Résumé
The three main performance metrics in automotive suspensions are passenger comfort, suspension deflection, and road holding ability. It is well-known that these three objectives can not be reached at the same time. In order to reach them "individually", three linear H-infinity controllers are designed. Ateach moment, the desired performance requirement is chosen with a robust stable control strategy that switches between the three linear H-infinity controllers. The switched control logic is not developed in this study.
