The invention discloses a suspension control system and a control method thereof, the suspension control system comprises a suspension system, a fuzzy adaptive PID controller, a magneto-rheological damping force limiter, a magneto-rheological damper controller and an inerter coefficient adjusting unit, and an inerter is a variable inerter inerter; the sprung mass acceleration sensor transmits a signal to the fuzzy controller to obtain a target damping force, the target damping force passes through the magnetorheological damping force limiter and then is input to the magnetorheological damper controller, and the magnetorheological damper controller provides an actual damping force for the suspension system; by designing an optimal controller, the unsprung mass acceleration xt '', the displacements xt-xb and xb-xr and the actual damping force are subjected to weighting processing, and the optimal inerter coefficient under the current road surface condition is obtained. According to the system and the method, wheel resonance can be converted into resonance of the inerter, the control method of the system is beneficial for independently controlling the inerter coefficient under different road conditions, combined control can be carried out on the system and the magnetorheological damper, parameters are adjusted in real time, and the optimal comprehensive performance of the all-road-condition system is achieved.
