N2 - This paper proposes a compound controller with composite anti-interference ability for a semi-active suspension system. A half-car semi-active suspension model is established considering both vertical and pitch motion. Then, the model is decoupled into various transfer function form so as to calculate controller transfer function in a more precise way. A compound controller is designed to control active force of front and rear suspension combining mix-type feedback controller and feedforward controller in order to minimize the influence of both road random disturbance and road sudden disturbance as much as possible. Finally, simulation is implemented and results show that comparing with passive-suspension system and conventional parallel PID controller, vehicle ride comfort, suspension controlling force and system anti-interference ability are obviously optimized.
