Abstract

This paper uses nonlinear control theory for the control of an electro-hydraulic active suspension. A 'sliding' controller is developed, combined with a parameter adaptation law, and implemented on a quarter car active suspension. Stability and robustness issues, as well as parameter convergence criterion will be discussed. The resulting performance is compared with that of a passive quarter car suspension. Simulation and experimental results at the natural frequency of the car body, 1 Hz, show that the controlled suspension performs better than the passive suspension in improving the ride quality of the quarter car system and parameter adaptation increases performance.
