Adaptive Aperiodic Intermittent Control for Nonlinear Active Suspension Systems

This paper proposes an aperiodic intermittent control method for nonlinear active suspension systems (ASSs). The dynamics of ASSs under the intermittent control is regarded as switched nonlinear systems composed of controllable and uncontrollable subsystems. An aperiodic adaptive intermittent control scheme can be presented to stabilize the attitude of the vehicle by using the backstepping technique and improve the comfort of passengers. Indeed, the objective is achieved via the tradeoff among the controllable and uncontrollable subsystems from the dwell time algorithm. Then, the performance of closed-loop ASSs can be analyzed by the Lyapunov theory. Finally, the effectiveness and rationality of the proposed method are verified from the simulation results.
