开关磁阻电机调速系统的主要研究 “开关磁阻电机(Switched reluctance motor简称SR电动机)”一词源见于美国学者S.A.Nasar1969年所撰论文,它描述了这种电机的两个基本特征:1开关性——电机必须工作在一种连续的开关模式,这是为什么在各种新型半导体器件获得后才得以发展得主要原因;2磁阻性——它是真正的磁阻电机,定、转子具有可变磁阻回路。

Because WDM networks are circuit Switched loss networks blocking may occur because of lack of resources. Also in circuit Switched networks many paths use the same links. This toolbox answers the question how different paths with different loads influence on each other and what is the blocking on each of the defined path. Toolbox is capable of computing blocking for three different WDM network types: with no wavelength conversion, with full wavelength conversion and with limited range wavelength conversion. It is worth noting that case for full conversion can be usefull for any circuit Switched network without additional constraints (i.e. wavelength continuity constraint in WDM), for example telephone network. Toolbox contains also scripts for defining network structures (random networks, user defined networks) and traffic matrixes. Three graph algorithms for shortest path computation are also in this toolbox (they are used for traffic matrix creation).

该文介绍了开关磁阻电机的基本原理,设计了一种用80C196 单片机实现的开关磁阻电机驱动系统,并对该开关磁阻电机调速系统的性能进行了实验与测试,实验证明该系统运行可靠。开关磁阻电动机是磁阻电动机与电子开关驱动控制器组成的控制装置,又称开关磁阻电机驱动系统(Switched Reluctance Motor drive,简称SRD)。电机结构简单坚固,运行可靠,系统具有启动转矩高、启动电流低、调速范围宽、运行效率高,特别适用于频繁启停及正反转运行,使得SRD 成为交,直流电机驱动系统以及无刷直流电机驱动系统的强有力竞争者。目前,SRD 已用于多个领域,如:电动车驱动、家用电器、伺服与调速系统等许多领域。本文设计了一个以 80C196 单片机为控制核心的SRD 的控制系统,充分利用了SRD 电机控制方式灵活的特点,采用数字化控制系统对SR 电机进行控制,简化了硬件电路,提高了系统的可靠性。
