Comparative Analysis of Control Methods with Model Reference Adaptive System Estimators of a Seven-Phase Induction Motor with Encoder Failure

This article presents a comparative analysis of the direct torque control with space vector modulation method for seven-phase squirrel-cage induction motor during encoder failure. The model reference adaptive system current and estimator system—flux based applied in loop speed have been analyzed. mathematical system-type estimators described. to voltage source inverter, controlled motor, has operation verified via simulation tests, results performed studies analyzed presented. authors’ original contribution work novelty includes comparison performance two estimators: novel estimator.
