Rotor Flux Estimation for Induction Motors Based on Modified Sliding Mode Observer
This paper presents a method for rotor flux estimation with direct applications in the control of induction motors (IM). We propose a new structure for the sliding mode observer (SMO) such that pure integral calculation for flux estimation is avoided. Simulation results, analyzed against performances of conventional SMOs, demonstrate that the proposed observer can directly estimate the rotor flux, and it is robust to parameter variations and load disturbance.
