A ride quality test for active suspension system is real significant in modern automotive suspension control performance validation for ride comfort evaluation
The Composite Nonlinear Feedback (CNF) controller is proposed as a control strategy to reduce the high overshoot on the transient response and fast settling time. The mathematical modeling of a MacPherson quarter car suspension is utilized in this paper. A chassis twists road procedure in ride quality test has been applied. The multi-body dynamics system software so-called CarSim is used for validation. The strength of the proposed control scheme is shown by numerical experiment results and numerical simulation results.
