Nonlinear control design for a semi-active vibration reduction system

This paper considers the control design for a vibration reduction system using semi-active actuators to improve the ride quality. The main challenge comes from the nonlinear dynamics, limited control authority, and lack of performance-oriented nonlinear control design results. Two nonlinear controllers are proposed and compared to a conventional semi-active control. Simulation shows the proposed controls provide a good balance of 2- and ∞-norm metrics.
