Three Two-Dimensional Fuzzy Regulators for PID Controller Parameter Tuning (Kp, Ki, Kd)

This system implements three two-dimensional fuzzy regulators to adjust the parameters (Kp, Ki, Kd) of a PID controller. The control principle involves fuzzifying input variables (error e and error change ec), performing fuzzy logic inference, and defuzzifying outputs through three fuzzy controllers FC1, FC2, and FC3 to determine PID parameter adjustments. Implementation typically involves defining membership functions for input/output variables and designing rule bases mapping (e, ec) combinations to parameter corrections.
