The paper presents a two-degree-of-freedom (2DOF) controller with a reference model following fuzzy adaptation for position control of an induction motor drive. First, an indirect field-oriented induction servomotor drive is implemented, and a 2DOF controller is designed at nominal case according to the given tracking and regulating drive specifications. Then the resulting closed-loop tracking transfer function is used as the reference model, and the 2DOF controller is augmented by a model-following error-driven fuzzy adaptation mechanism to reduce the effects of parameter variations on the desired performances. The effectiveness of the proposed controller is demonstrated by simulated and experimental results.
