The invention aims to provide a sliding mode control system and method for a magnetorheological damping suspension based on a fuzzy disturbance observer. The sliding mode control system comprises a sliding mode controller, the disturbance observer, a fuzzy controller, a superposition module and a magnetorheological damper inverse model. The sliding mode controller and the disturbance observer calculate output control force data and compensation force data according to input suspension vertical displacement, suspension vertical speed, tire vertical displacement and tire vertical speed data, and output the control force data and the compensation force data to the fuzzy controller; the fuzzy controller adjusts the input control force data and compensation force data, then feeds the data back to the sliding mode controller and the disturbance observer to obtain the adjusted control force data and compensation force data, then superposes the adjusted control force data and compensation force data to obtain hysteresis damping force data, converts the hysteresis damping force data into current through a magneto-rheological damper inverse model, and finally outputs the current through the magneto-rheological damper inverse model. The current is input into the magnetorheological damper to control the magnetorheological damper to output damping force. According to the invention, the riding comfort and the driving safety of the automobile can be effectively improved.
