Abstract
A simplified approach to continuous, online tuning of rotor flux feedforward, field-oriented induction machine drives is presented. The procedure offers the advantages of not requiring a special test signal or special test conditions. The approach takes advantage of the stator voltage equations, which allow robust, parameter-insensitive estimation of the electromagnetic torque while operating at nominal speeds for which the stator voltage (IR) drop is negligible ( mu approximately 5 Hz and above). This torque computation is independent of the rotor flux field-oriented control. In essence the approach uses a stator flux controller to detect improper tuning of the feed forward, rotor flux controller. The authors present the theoretical and practical implementation of such a continuous, self-tuning system. Experimental results are based on a rotor flux feedforward, field-oriented induction machine servo drive.Keywords
