摘要
分析了基于定子磁链定向的间接定子量控制原理,采用Matlab6.5/simulink软件,按实际控制系统建立异步电动机快速转矩控制系统的动态仿真模型,在全速域分析了基于定子磁场削弱的间接定子量控制系统的动、静态响应。仿真结果表明定子电流为正弦波,且谐波和转矩脉动小,并具有良好的稳、动态响应性能。
The principle of stator-flux-odented indirect stator-quantities control was analyzed. The dynamic simulation model of indirect stator-quantities control for asynchronous motor was established according to actual control system by using matlab6.5/simulink soft. The dynamic and static response of indirect stator-quantities control system was analyzed based on dynamic stator flux field-weakening technology. Simulation results show the stator current is with few harmonics, the torque has small ripple. The control scheme is viable and had good dynamic and steady response performance.
