摘要
提 出了异步电机矢量控制中定子电流的自适应内模控制（ＩＭＣ）及调节器的设计方法。首先，根据ＩＭＣ原理设计异步电机电流调节器，用矩阵奇异值分析了ＩＭＣ电流调节器的鲁棒性，然后用最小二乘法对模型参数进行辨识。最后将其应用于异步电机转子磁场定向的矢量控制中。通过对电流调节器传递矩阵函数的仿真及用ＤＳＰ实现的异步电机矢量控制运行实验，验证了自适应ＩＭＣ电流调节器的良好性能。
The adaptive internal model control approach is applied to the current regulation of indirect rotor flux oriented control (IFOC) of induction motors.The design methodology of current regulator is presented based on the model of induction motors in the synchronous flame and its dynamic and robust characteristics are analyzed using matrix singular values. The parameters of the IMC based current regulator are estimated using in method.Also, the simulating and experimental results verified the good performances of the adaptive internal model current control in the IFOC induction motor.
