ADAPTIVE RIDE CONTROL IN ACTIVE SUSPENSION SYSTEMS

The paper describes the development of an adaptive control algorithm f or active suspension systems based on optimal regulation methods. The objective is to design an algorithm which will automatically tune at s tart-up to changed vehicle conditions and adaptively re-tune to change s in driving conditions (in particular road generated disturbances). T he proposed algorithm is a self-tuning regulator based on generalised minimum variance (GMV) control. Simulation results obtained for a 3 de gree-of-freedom (DOF) quarter car suspension demonstrate potential ben efits of fully adaptive control in automotive suspensions.
