Sensorless Vector Control of Dual Star Induction Machine Using Sliding Mode Flux Observer

This paper presents the vector control of a double-star induction machine (DSIM) using a sliding mode flux observer (SMFO). The vector control strategy is often sensitive to changes in machine parameters, and the real-time measurement of these parameters increases the cost of the system. To overcome these drawbacks, a sensorless DSIM operation can be achieved using an SMFO, which provides robust control against parameter variations without requiring speed and stator flux sensors. Simulation tests were conducted in the MATLAB/Simulink environment to demonstrate the effectiveness of the proposed structure. Finally, the simulation results are recorded and analyzed.
