摘要
通过对变频调速永磁电机矢量控制的介绍,论述了采用新的控制方法既矢量控制理论进行控制时,电动机具有和直流电动机类似的特性。通过改变电枢电流便可以实现对转矩的控制。而其控制方法主要是恒转矩控制和普通弱磁控制,其控制系统采用电流、转速的双闭环控制。
Based on the introduction of vector control of variable-frequency speed permanent magnet synchronous motor, kind of motors are similar to that of dc motors adjustablethis paper expounds that characteristics of this when a new control method （ i.e. vector control theory） is adopted. Changing the armature current of the motor can achieve the control of torque, its control method mainly is constant torque control and common weak magnetic control, and its control system adopts doubly-closed loop control of current and speed.
