The Novel Control Strategy And Drive System For Switched Reluctance Motors

The Switched Reluctance Drive system (SRD) has gain a great development as a novel kind of variable-speed drive systems after 1980s. And it attracts more and more attentions for its excellent performance and great potential commercial value.This paper is completed based on two projects. One is titled "The novel control strategy and drive system for switched reluctance motor", which is supported by the Department of Science & Technology of Zhejiang province. The other is supported by EMERSON Network Power co., Ltd as an advanced research project. And this paper mainly introduces how to design and realize a four-quadrant running SRD system to control a 3KW SRM (8/6 poles) based on a DSP(tms320f240), which uses H-bridge power convertor and power-consumption braking method.The basic working principles and characteristics of SRM will be described firstly in this paper, as well as its developing survey and researching directions. And then the SRD system will be separated into several function parts to be introduced respectively in details: (1) To analyze the basic characteristics of the SRM including electromagnetism, current and torque of every angle field of the rotor based on the subsection-linearized inductance characteristics of stator windings and several idealized supposes. (2) How to design and realize the H-bridge converter, and the method to use it; (3) How to design and realize the controller based on DSP(tms320f240) and the control strategies, as well as the program; (4) To introduce the monitor program running in a PC, which is programmed by DELPHI. And at last, the paper will also introduce the method to test the SRD system and the results.
