Design of SRM System Based On SCM Control Systems
Abstract
Switched reluctance motor drive system(Short title SRD) is variable speed system with
the development of microelectronics power electronics,computers, the rapid.It switched reluctance motor, power electronics, control technology for the integrated not only maintain the structure of AC induction motor is simple, rugged, reliable and controllable DC motor has a good advantage but also speed AC drive system and DC system Can not match the significant features. Thesis based on four-phase 8 / 6 poles 5.5KW SRM as the research object, completed a microcontroller as the core component of the control system design. The system uses the PWM control mode, use split DC power converter main circuit power supply, the main switching devices used IGBT, the drive circuit used EXB841 driver module. MCU C8051F320 as the core of the controller. Mainly on the current detection, position detection, fault protection and other peripheral circuits and display circuits were designed, with the flow, over-voltage protection function. The design also uses the modular programming method to enhance the readability and ease of maneuverability.
Key words: switched reluctance motor; SCM; power converter; switched reluctance motor control system
