Position tracking of the induction motor without rotor velocity or rotor flux measurements

摘要

We design a partial-state feedback, rotor position/rotor flux controller for the full-order, nonlinear dynamic model of an induction motor. The singularity free controller does not require measurement of rotor flux or rotor velocity and yields global exponential rotor position and rotor flux tracking. Experimental results are included to verify the effectiveness of the proposed controller.
