The invention discloses a start control method and device for a switch reluctance motor. The method comprises the steps of acquiring the current torque signal and the current rotating speed signal outputted by the switch reluctance motor which is in a rotating speed control mode during starting; treating a PID regulator as a speed closed-loop regulator G1, wherein the parameters are K11, K12 and K13; adjusting the PID regulator as a current closed-loop regulator G2, wherein the parameters are K21, K22 and K23; treating one function/ transfer function as a parameter adjusting module G; adjusting the parameters of the G1 and the G2 according to the current output torque T and the rotating speed v of the switch reluctance motor; expressing through a matrix equation which can be shown as [K11K12K13; K121K22K23]T=G([T v] T). The control method comprises an acquiring module SA, the speed closed-loop regulator G1, the current closed-loop regulator G2 and the parameter adjusting module G. With the adoption of the method and the device, the operation is smooth while starting on a flat road or starting on a slope, and slipping, jittering and colliding can be avoided.
