the dissertation is organized as follow : first, the characteristics of srm and its control system's development are introduced . previously major methods used to implement non-position sensor detection and the significance of making search for this direction is generated . and the configuration and fundamental operating principle of srm are analyzed; some study of linear model and nonlinear model with phase coil as fundamental parameter are presented and sr's linear model and nonlinear model are set up 本文就以上兩個問題進行了深入研究,首先介紹了sr電機及其控制系統(tǒng)的發(fā)展歷程,研究無位置傳感器srd的意義和總結已有的無位置傳感器檢測方法,并且通過分析sr電機的結構和運行原理,研究sr電機繞組的線性電感模型和非線性電感模型,建立了電機的線性和非線性數(shù)學模型,重點研究sr電機的非線性模型,為sr電機運行與控制特性的研究和仿真研究奠定了理論基礎。
