The invention discloses a control system for a switch reluctance motor in the technical field of elevators. The control system for the switch reluctance motor comprises a rotor and a stator which are arranged coaxially. The front and rear ends of the rotor are respectively and uniformly distributed with four tooth poles without windings. The front and rear ends of the stator are respectively and uniformly distributed with six tooth poles with windings in a corresponding manner. The phase difference in the peripheral direction between the tooth poles at the front and rear ends of the rotor is 45 degrees. The tooth poles at the front and rear ends of the stator are arranged in the same phase in the peripheral direction. Windings on the two tooth poles which are counter to each other in the radial direction on the stator and a silicon controlled rectifier are in series connection at two ends of a power supply. Control electrodes of the silicon controlled rectifier are respectively connected to the output end of a controller. Control signals are sent by the controller in time sequence to conduct the corresponding silicon controlled rectifier. When the rotor is in unidirectional rotation, the phase angle between the silicon controlled rectifier which is conducted every time and follows a coil and the corresponding tooth poles without windings is the minimum. According to the control system for the switch reluctance motor, a logical control mode is adopted, so that the motor is operated more smoothly with lower noises during operation.
