Abstract

The robust control of an AC induction servo drive is examined. The linear-quadratic-Gaussian with loop-transfer-recovery (LQG/LTR) methodology is used for the servo compensator design to improve the drive performance and meet the stability-robustness specifications in the frequency domain. Based on the principle of indirect field orientation, a simplified model of the current-decoupled induction drive is constructed and used for the design of the proposed servo control scheme. Experimental results are presented to show that LQG/LTR design is a viable approach, and that problems associated with the parameter variation, plant uncertainty, and load disturbances can be solved.
