Abstract

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.

Description

technical field [0001] The invention relates to the field of electric vehicle control, in particular to a starting control method and device for a switched reluctance motor. Background technique [0002] The switched reluctance motor is an excellent motor system for vehicles. Its own principle ensures that it has high reliability, high efficiency and wide speed regulation range. It is very suitable as the main drive motor of electric vehicles. [0003] The switched reluctance motor generally adopts a double closed-loop control structure, including a current closed loop and a speed closed loop. The current closed loop is the inner loop, and the speed closed loop is the outer loop. The current closed-loop and speed closed-loop of the switched reluctance motor generally use a PID regulator, which consists of three links: proportional, integral and differential, and the parameters of the three links need to be preset when used. The current closed-loop collects the winding curre...
