Comparative Analysis of PI Controller versus Fuzzy Logic Controller for Dual Star Induction Machine Speed Regulation

A performance comparison study between Proportional-Integral (PI) and fuzzy logic controllers for speed regulation of a Dual Star Induction Machine (DSIM). The system employs two PWM voltage source inverters (VSI) with field-oriented control (FOC) decoupling. Simulation results demonstrate controller behavior under parameter variations, with implementation details including error calculation algorithms, fuzzy membership functions, and PWM signal generation routines.
