Performance Improvement of Induction Motor Drive Using Feedback Linearization and Fuzzy Torque Compensator with RTDS Implementation

摘要

This paper proposes a feedback linearization scheme for performance improvement of induction motor drive. This scheme decouples the rotor flux and the torque using P-I controllers with feedback linearization scheme. The control scheme is implemented in a stationary reference frame. P-l controllers for speed and flux loop are systematically designed. To reduce torque ripple and to improve torque and speed responses fuzzy torque compensator is designed with 16 fuzzy rules. The control scheme is simulated in SIMULINK environment and implemented in RTDS environment. Proposed scheme with P-l controllers and with fuzzy torque compensator are compared. Simulation results are validated with RTDS test results.
