HIGH PERFORMANCE ADAPTIVE FIELD-ORIENTED MODEL REFERENCE CONTROL OF CURRENT-FED INDUCTION MOTOR

Noureddine Goléa - Amar Goléa

   This paper develops the application of an adaptive model reference approach to the direct field-oriented control of the current-fed induction motor. The proposed algorithm decomposes the control task into three loops, namely, the speed loop, the d-axis flux loop and the q-axis flux loop. In this way the matching conditions are always fulfilled. Then, a model reference tracking adaptive control is designed for each loop. Proportional-Integral update laws are used to adjust the control parameters, which increases the tracking performance. As compared to standard adaptive control schemes, no special knowledge about the drive parameters is required. Extensive simulation studies have shown good robustness against parameter variations, high tracking performance and simplicity of implementation.
