The design of robust adaptive controller applied in automobile active suspension

This article proposes a new robust adaptive control algorithm from applied point of view which can be applied to active suspension. Its stability is proved and simulated in disturbed system. Firstly, a nonlinear filter is introduced. It simplifies the control law design. Secondly, the analysis of VSC (variable structure control) is used in backstepping controller design. The robustness to system disturbance is gained.
