Speed Estimation Stator-field-orientation-controlled Induction Motor Drive with Resistance Parameter Identification

control (MRAC), stator resistance parameter identification, fixed trace algorithm (FTA)A stator resistance parameter identification was proposed for the speed estimation statorfield-orientation-controlled (SFOC) induction motor (IM) drive.The decoupled SFOC IM drive was formulated on the basis of stator current and flux to achieve maximum torque-per-ampere control, with the stator currents measured using Hall-effect current sensors.An adaptive speed estimation approach based on model reference adaptive control (MRAC) was developed by utilizing the motor's reactive power.To address resistance variations induced by temperature changes, an online stator resistance identification method employing the fixed trace algorithm (FTA) was integrated into the SFOC IM drive.The complete simulation model was implemented using the MATLAB /Simulink environment, and the control algorithms were realized on a TI DSP 6713-and-F2812 platform to validate the proposed method.Both simulation and experimental results confirmed the effectiveness of the proposed approach.
