INTELLIGENT SENSORS BASED ON ESTIMATORS AND INTERPOLATING IMPLEMENTATION FOR FLUX AND TORQUE MEASUREMENTS

Toma Leonida Dragomir, Gheorghe Daniel Andreescu

Abstract

The paper develops and compares intelligent sensors for flux and torque estimation in permanent magnet synchronous motors (PMSM) based on combined voltage-current flux estimators and interpolating implementation. Typical applications are in the direct torque and flux control (DTFC) and in the field-oriented vector control of ac drives. Simulation results using a PMSM drive system prove good dynamic performances of the flux and torque sensors to parameter deviations in wide speed range.
