Sliding Mode H∞ Control for Active Vehicle Suspension Systems
This paper is concerned with the sliding mode H∞ control for an active vehicle suspension system.The suspension system is first decomposed into two virtual subsystems via a linear transformation.By considering the tire deflection of the suspension system as a virtual control for the first subsystem,the virtual state feedback H∞ controller is derived.Then,based on the virtual H∞ controller,a novel sliding mode surface is proposed.Third,a sliding mode H∞ controller is designed to ensure that the state trajectories can reach the sliding surface in finite time and maintain on it thereafter.Simulation results show that the designed controller can achieve the specified H∞ performance for the active suspension system and preserve the asymptotic stability of the closed-loop system.
