Abstract : "Technique of optimal vibration control and simulation for vehicle active suspension systems is developed. Considered the nonlinear damping of springs, mechanical model and nonlinear dynamic system for a class of tracked vehicle half-car suspensions vibration control are established and the corresponding system of state space form is described. In order to prolong the working life of suspension system and improve ride comfort, based on the active suspension vibration control devices and used optimal control approach, an optimal vibration controller is designed, and an algorithm is presented for the vibration controller. Numerical simulation results illustrate the effectiveness of the proposed technique."

Keyword : Nonlinear system, optimal control, suspension system, vibration control.
