Linear switched reluctance motor control system and control method thereof

Abstract

The invention relates to a linear switch reluctance machine control system and a linear switch reluctance machine control method. A position controller sends a first control signal to a communicationnetwork device, so that the communication network device sends out a second control signal to control a driving device to send out a driving signal to drive two motor modules of a reluctance machine device; a sensing device senses the motor position and speed of the reluctance machine device and acquires sensing signals of the motor position and speed; the communication network device calculates afirst transmission latency from the reluctance machine device to a position controller according to the sensing signals; the position controller adjusts the first control signal according to the position and speed of the motor and the first transmission latency; the communication network device also calculates a second transmission latency from the position controller to the reluctance machine device and adjusts a second control signal sent by the communication network device according to the second transmission latency and the first control signal, so that the driving device also adjusts a driving signal sent by the driving device according to the second control signal, and further the two motor modules of the reluctance machine device achieve synergic movement.

Description

[0001] 【Technical field】 [0002] 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. [0003] 【Background technique】 [0004] With the rapid development of intelligent and highly integrated control chips, linear motion control systems are popular in modern industrial applications due to their fast, high-precision and batch processing performance. As an indispensable power device in the linear motion control system, the motor, especially the appearance of the linear switched reluctance motor, not only has the advantages of large starting torque, strong overload capacity and wide speed range, but also in some linear motion occasions. It has unique advantages. At the same time, the emergence of a series of network control systems (NCS), compared with traditional point-to-point control systems, has the advantages of low cost, weight reduction, easy installation and low main...

Problems solved by technology

For example, in the structural schematic diagram publicized in the Chinese invention patent application (patent application number: 201510246003.8, invention name: a linear switched reluctance motor position control system), a display module is used to display the output position and speed of the motor, micro The reference signals in the controller are preset in advance, but the network control system is not introduced, and the detection and control adjustment of the motor parameters by the host computer cannot be realized.

At the same time, there are still some challenging problems based on the network that have not been fully studied, such as the method of obtaining the motor model, the inevitable motor parameter errors caused by the motor parameter identification method, and the cooperative work between different motors. , nesting problems between different motors, etc.
