This paper presents control characteristics of a commercially available magnetorheological (MR) damper which can be directly applied to passenger vehicles. After evaluating the field-dependent damping force, the damping force controllability is experimentally investigated. Subsequently, a quarter-car model which is composed of sprung mass, MR damper, spring and tire is constructed and the governing equation of motion is derived in order to investigate vibration control of a vehicle. A discrete-time fuzzy sliding mode control algorithm is then designed by considering system uncertainties such as the variation of the sprung mass. The controller consists of a discontinuous part and an equivalent part. In addition, the fuzzy algorithm is adopted to increase system robustness to the uncertainties and achieve faster reaching to the sliding surface. Control performances of the proposed sliding mode controller are experimentally evaluated under various road conditions and compared with continuous-time sliding mode controller.
