摘要

提出了一种保证整个弱磁场区域内每安培转矩最大的感应电机控制方法。研究了电机的输出转矩能力与漏感的关系。通过根据磁通水平、限流和限电压调整弱磁场运行的基本转速，可以实现平稳、精确地过渡到弱磁场运行。通过5马力实验室感应电机驱动系统的仿真和实验验证了该方案的有效性。

Maximum torque control of an induction machine in the field weakening region

An approach to induction-machine control which ensures maximum torque per ampere over the entire field weakening region is presented. The relation of the output torque capability to the leakage inductance of the machine is examined. By adjusting the base speed for the field weakening operation according to the flux level, the current limit, and the voltage limit, smooth and precise transition into the field weakening operation can be achieved. The proposed scheme is verified through simulation and experiment for a 5 hp laboratory induction motor drive system.<>
