Abstract

In this paper, a complete close-loop speed sensorless dual-motor drive system was designed based on the dynamic model and an adaptive observer which is based on MRAC was applied to each induction motor, in which stator fluxes, rotor fluxes and motor speeds were estimated. The validity and effectiveness of this proposed method were confirmed through different balanced and unbalanced load tests of simulations
