摘要：

A simplified approach to the continuous on-line tuning of rotor flux feedforward field-oriented induction machine drives is presented. The new 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 IR voltage drop is negligible (≈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 feedforward rotor flux controller. The theoretical and practical implementation of such a continuous self-tuning system are presented. Experimental results are based on a rotor flux feedforward field-oriented induction machine servo drive. © 1990 IEEE
