self-tuning Fuzzy PID decoupling controller for VAV Air-Conditioning System

Variable-air-volume (VAV) air-conditioning systemis a multi-variable system and has multi coupling control loops.A multivariable decoupling PID controller is designed for VAVair-conditioning system. In general, an adaptive fuzzy PIDcontroller (AFPIDC) means that the PID parameters areadjusted by fuzzy rules in real-time. Since the output of thefuzzy logic controller is changeable, the gain of the controller isadjusted implicitly and adaptively. The simulation results showthe validity of the proposed approach
