摘　　要：混合励磁电机在保留永磁电机许多优点的同时,能克服永磁电机气隙磁场难于调节的缺点。当前,对混合励磁电机的研究主要集中在混合励磁的原理分析、电机基础理论分析等方面,而对电机的控制策略、调速方法等方面的研究相对较少。混合励磁双凸极电机是一种磁通可控的定子永磁型双凸极电机,根据该电机的运行原理建立了采取分区控制策略,实现调压、调磁、调速之间动态、协调控制的Matlab仿真控制系统。仿真结果表明:采用分区控制策略,增磁时可以提高系统的响应速度,弱磁时可以有效拓宽电机的调速范围,从而能满足在电动汽车等需宽调速范围的应用场合。Hybrid excitation machine has the advantages of PM machines and overcomes its shortcomings of difficult in flux regulating. At present, researches on hybrid excitation machine mainly focus on the principle analysis and motor＇s basic theory analysis of hybrid excitation. However, there are relatively few researches on the control strategy and speed regulating methods of motors. Hybrid excited doubly salient Machine is a kind of flux-controllable permanent-magnet brushless （PMBL） motor. According to the operating principle of this kind of motors, Matlab simulating control system was established. This Matlab simulating control system adopts division control strategy and realizes the dynamic and coordination control among voltage regulating flux regulating and speed regulating. Simulating result shows that by adopting division control strategy, the response speed of the system will be enhanced while flux is increased, and the speed regulating scope of the motor will be efficiently broadened while flux is decreased. Thus it can meet the needs of applying situations where wide speed-regulating scope is needed such as electric automobiles.
