Analysis In Starting Process Of SRM

The structure of Switched Reluctance Motor is simple, with wide speed range and good performance, and it is also in the entire speed range with high efficiency. It has been paid widespread attention in recent years. However, its special structure with big noise and big torque ripple is still a problem. This paper starts from starting process of view to explore the improvement of Switched Reluctance Motor.How to resolve the. problem of the starting process of switched reluctance motor,as well as the problem of the link-up after starting process is an important part of the research of the contol in switched reluctance motor.This paper analyses the problem of the starting process of switched reluctance motor,and put forward a proposal to solve the problem.Using two phase start-up method to experiment,and simulate the start-up process of SRM by matlab.Analysis of the starting current ,torque ,speed and other parameters.Gains better experiment waveform.Confirmed that the SRM running stable and reliable during the start-up process.This paper describes TMS320F2812 DSP as the core controller. The design of SRM control circuit includes the main control module, power converter, current detection module, voltage detection module, speed detection module and other auxiliary circuits. This paper also describes the design of the entire system software. Control system software worked in the CCS2.2 environment, used C language to compile the current chopper procedures, and directed torque procedures and other relevant subprogram; it has realized the motor current chopper start and has laid the foundation for further research.
