Switched Reluctance Motor Dsp-based Experimental Platform Design

As the representative of modern electrical machines, switched reluctance machine combines the electrical machine theories with the modem power electronics technique and the advanced microprocessor control technique, which not only has low-cost strong structure, good fault-tolerant and heat-resistant capability but also has excellent controllability. Thus, switched reluctance machine as motor is widely used in drive and speed regulation field.This paper mainly focuses on the design of the experimental platform for switched reluctance driver based on DSP, and has done some further theoretic research as well as experimental research.Firstly, this paper summarized and analyzed the advantages of SRD, further made the significance of developing this knowledge of SRD system clear.Secondly, this paper summarized how switched reluctance generator works and how to control it and the compare based on each control principle.Thirdly, in this chapter, the linear and nonlinear mathematic models of SRM were discussed in details. Simulation of SRM using MATLAB software and a series of qualitative analysis were conducted.Fourthly, a set of practical SRD system for experimental is developed, which based on DSP control technique and power electronics converting technique. The reasonable design of this system fully displayed the flexibility of SRD control.Finally, experiments have been done on this practical system. The experimental results validated and deepened the conclusions drawn from theoretical research. The compare between the results from experiments and simulation also testified the practicability of the mathematical models presented in this paper. The results fully approved the usability and reliability for the system. It helps a lot to the efficiency of experimentation.
