The invention relates to a particle swarm-time lag dependent H-infinity robust controller design method for vehicle magneto-rheological semi-active suspension shock absorber response time lag control,and belongs to the field of vehicle suspension control. The method comprises the steps of: constructing a system motion state equation, an output equation and a state feedback measurement equation according to the 1/4 vehicle magneto-rheological semi-active suspension model containing the shock absorber response time lag, so that a time-lag independent H-infinity robust controller and a time-lagdependent H-infinity robust controller are constructed; and establishing a particle swarm-time delay dependent H-infinity robust controller by taking the maximization of the comprehensive performanceof the relative time delay independent H-infinity robust controller as a target, and solving the particle swarm-time delay dependent H-infinity robust controller, so that the ideal variable control force of the suspension system is obtained, and control over the vehicle magneto-rheological semi-active suspension with the shock absorber response time lag is achieved. The controller designed by theinvention is high in robustness and strong in external interference resistance, can accurately control the magneto-rheological semi-active suspension system containing the time lag of the shock absorber, and can ensure that the performance index of the suspension system is improved to the maximum extent.
