Simulation of Indoor Temperature Control in VAV Air Conditioning System Based on Fuzzy PID and Smith Predictor Controller

Abstract:

A Fuzzy PID-Smith Control algorithm is proposed based on Fuzzy PID Control and Smith Predictor Control for the indoor temperature control of VAV air conditioning system which is a big inertia, pure time-delay, nonlinearity and greatly affected by circumstances complex temperature system. The algorithm flow and fuzzy reasoning rules were designed and it possesses the advantages of both Fuzzy PID and Smith Predictor. The simulation results show that the algorithm has fast response, small overshoot, high accuracy, strong robust and self-setting in line when the parameter changes and a great improvement in the aspects of overshoot and adjusting time has been achieved compared to the current control algorithm.
