Three Two-Dimensional Fuzzy Regulators Implement PID Controller Parameters Kp, Ki, and Kd

This system employs three two-dimensional fuzzy regulators to adjust the PID controller parameters Kp, Ki, and Kd. The control principle involves fuzzifying inputs based on error (e) and error change rate (ec), performing fuzzy logic inference, and defuzzifying outputs through three fuzzy controllers (FC1, FC2, FC3). The implementation typically involves: 1) Defining membership functions for e and ec inputs 2) Creating fuzzy rule bases for each parameter 3) Using centroid method for defuzzification to generate precise PID parameter adjustments.

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.
