Abstract :
The problem of optimal vibration control for vehicle active suspension systems under road roughness disturbance is considered. Firstly, the nonlinear models for two-degree-freedom quarter-car suspension system and road roughness disturbance are built. Then, based on the theory of successive approximation approach (SAA), the nonlinear optimal control law is designed. A state observer is constructed to make the feedforward compensator physically realizable. Numerical simulations illustrate the effectiveness of the optimal control law.
