The invention relates to a linear switched reluctance motor control system and a control method thereof. The linear switched reluctance motor control system comprises a position controller, a drivingdevice, a reluctance motor device and a sensing device, the position controller is used for emitting a control signal to the driving device to enable the driving device to emit a driving signal to drive a reluctance motor device so that the motor position and speed of the reluctance motor device can be controlled, the reluctance motor device is connected with the position controller through the sensing device to enable the sensing device to feed back a detection signal of the motor position and speed to the position controller so that the position controller adjusts the control signal emittedby the controller according to the motor position and speed, and stability conditions and the gain K of the system are calculated through the stability analysis theory, the vectorization method and the H representing technology so that the position controller outputs the control signal according to the stability conditions and the gain K obtained through calculation.
Description
【Technical field】 [0001] The invention relates to the technical field of motor control, in particular to a linear switched reluctance motor control system and a control method thereof. 【Background technique】 [0002] With the increasing demand for high-speed and high-precision motion, various types of linear motor-driven motion systems have received attention due to precise motion control. In recent years, some results have been presented for linear switched reluctance motor (LSRM) control systems, for example, a flux-fed reluctance actuator linearization scheme has been described based on cascaded analog sensing coils and digital Hall probe feedback control . [0003] The linear motion control system based on the principle of minimum reluctance is widely used in various industrial applications such as parts assembly, printed circuit and plate drilling, etc., with high speed, high precision, fast response, no path error, large output, linear execution, etc. However, it is ...
