Abstract
This paper focuses on the problem of vibration control for vehicle active suspension systems. According to the characteristics of the independent suspension system in vehicles, we decompose the suspension system into two subsystems from the perspective of practical. To complete the design of the vibration controller, we design a decoupling control law with respect to disturbances and a stabilization vibration control law for the car body subsystem respectively. The performance analysis shows that the designed controller has the function of feedforward control in theory, and can improve the performance of the suspension system significantly. Simulation results show the effectiveness of the proposed design approach.
