The invention relates to a control system comprising a smooth switching device for a switching reluctance control mode. The control system comprises a speed PI regulator, a control mode smooth switching device, a current detection module and a reluctance motor, wherein the current detection module is used for detecting current feedback Ifb output by the control mode smooth switching device, and the control mode smooth switching device receives input current Icmd of the speed PI regulator and a switching instruction, smoothly switches the control mode according to the switching instruction andoutputs an instruction to control the reluctance motor. The control system has the beneficial effects that the switching reluctance motor can be smoothed when the control mode is switched, and by smoothing during control mode switching, the impact brought by instantaneous switching can be effectively reduced, and the output torque can be stable at the moment of switching, thereby reducing the impact on the external machinery when the control mode is switched.
