分析了基于定子磁链定向的异步电机间接定子量控制的原理,通过磁链的幅值和位角增量来计算空间电压矢量。以定子磁链和转子磁链为状态变量,构造了感应电机全阶磁链观测器。并采用Matlab对该控制方案进行仿真,结果表明,基于全阶磁链观测器的间接定子量控制系统有很强的鲁棒性,且具有较好的动态和稳态性能。

The principle of stator-flux-oriented indirect stator-quantities control of asynchronous motor is analyzed, and the space voltage vector is calculated according to the phase increment and range increment of stator flux. A full order flux observer of induction motor is constructed with stator flux and rotor flux as state variables. The control method is simulated with Matlab, the result shows that the indirect stator-quantities control system based on the full order flux state observer has strong robustness, and also has good dynamic and steady response oerformance.
