摘　　要：分析异步电动机间接转矩控制(Indirect Stator-quantities Control,ISC)的基本原理,在定子坐标系内分别计算了定子磁链和转矩,得到定子磁链的幅值增量和相位增量,通过增量值计算出电压空间矢量。采用MATLAB对系统进行仿真,结果表明定子电流为正弦波,电磁转矩的稳态性好,系统具有良好的稳定性和动态性能。The basic principle of Indirect Stator-quantities Control(ISC)of asynchronous motor is analyzed.The stator flux and torque are calculated respectively in the stator coordinate system,the amplitude increment and phase increment of stator flux are obtained,and the voltage space vector is calculated through the increment value.Matlab is used to simulate the system.The results show that the stator current is sine wave,the electromagnetic torque has good stability,and the system has good stability and dynamic performance.
