永磁同步电动机的磁场定向控制及其实现

Field-Oriented Control and its Realization for Permanent Maqmetic Synchronous Motor

介绍了永滋同步电动机的磁场定向控制原理,指出磁场定向控制实际上可以简化为转子位置控制,给定电流的相位应根据转子的实际位置而定。对于双闭环交流调速系统,文中着重介绍了三相给定电流输出电路的工作原理。

The principle of field-oriented control of permanent magnetic synchronous motor is introduced. The field-oriented control can be simplified as rotator position control. The given current phase can be decided according to the practical position of the rotator. This paper introduces the principle of 3-phase given-current outpunt circuit in double closed-loop AC SR system.
