Abstract: In this paper, the fuzzy-scheduling control scheme, including the feedback of states and the integral of tracking error, is proposed for induction servo motor. Considering the saturation phenomena of control inputs, regional stability is discussed, where a T-S model is dealt with. It is noted that the saturated signal is represented as a perturbed one, which can be further investigated for the resulting robustness. To evaluate the control performance, a DSP-based induction motor is set up. Experimental results, associated with versatile command profiles and load conditions, illustrate that the proposed system has satisfactory performances in the viewpoint of disturbance rejection.
