This paper presents an LMI based robust H-infinity control scheme for constrained systems with normbounded uncertainties.The uncertainties are incorporated in the evaluation of the H-infinity norm and the time-domain constraints.The robust closed-loop properties inclusive of stability,H-infinity performance and the satisfaction of the timedomain constraints are discussed.Analysis and simulation results for a 2 DOF quarter-car model show possible improvements on ride comfort,while robustly respecting safety related constraints such as good road holding,limited suspension strokes and actuator saturation.
