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

This system utilizes three two-dimensional fuzzy regulators that respectively adjust the PID controller parameters Kp, Ki, and Kd. The control mechanism operates by processing the preceding error (e) and error change rate (ec) through three fuzzy controllers (FC1, FC2, FC3), which sequentially perform fuzzification, fuzzy logic inference, and defuzzification. In code implementation, this would typically involve: creating fuzzy inference systems (FIS) with input variables for e and ec, defining output variables for each PID parameter, establishing rule bases like "IF e is Large AND ec is Small THEN Kp is High", and finally applying defuzzification methods such as centroid calculation to produce precise adjustment values for PID parameters. This design ensures system stability and precision, delivering optimal performance across various practical applications through adaptive parameter tuning. The fuzzy controllers dynamically optimize PID parameters based on real-time system behavior, making the control system more robust against nonlinearities and disturbances.
