摘　　要：针对由电压源型逆变器供电的感应电机，提出了一种适于数字实现的离散化定子电流控制方案，与现有的定子电流控制方案相比它具有以下优点：１）对电机参数及电机运行状态变化鲁棒性好；２）对定子电流参考信号的动、静态跟踪性能好；３）与转子回路的状态变量及参数无关；４）控制算法简单，适合于计算机实现。仿真及实验结果证明了该方案的有效性。该定子电流控制方案的提出为现代高性能感应电机交流调速系统的实现提供了新的手段。For the induction motor supplied with the voltage source type inverter, this paper proposes a discrete stator current strategy which is provided with the following features in comparison with traditional methods: 1) good robustness against the changes in the parameters and operation conduction of the motor; 2) excellent follow to the given; 3) independence of the rotor parameters and variables; 4) simpler algorithm. Results of simulation and experiment illustrate that the stator current control strategy is practicable. This scheme offers a new means for developing high performance drive systems for induction motors.
