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 本文首先介紹了srm的基本工作原理和特點(diǎn)以及srd系統(tǒng)發(fā)展概況和研究方向,然后以srd的功能構(gòu)成為線索分部分進(jìn)行介紹: ( 1 ) srm的特性及控制策略分析,在電感分段線性化等簡(jiǎn)化條件下分析得出了各個(gè)轉(zhuǎn)子位置角度區(qū)間的電磁、電流和轉(zhuǎn)矩特性并分析了控制策略; ( 2 )分析設(shè)計(jì)了h橋式功率變換器的設(shè)計(jì)和工程實(shí)現(xiàn)的方法,并設(shè)計(jì)了基于這種功率變換器的換相邏輯; ( 3 )分析設(shè)計(jì)了以dsp為核心的控制器以及控制方法,并介紹了該控制器的軟硬件實(shí)現(xiàn); ( 4 )介紹了如何用delphi編制實(shí)現(xiàn)上位機(jī)監(jiān)控程序。
