Abstract

An expert fuzzy-PID fusion type controller is designed for VAV air conditioning system base on plenty of experience of practical projects. The principle of a typical VAV air conditioning system is introduced firstly. And the control characteristic curves of different VAV terminal units are given. The design thinking and course of expert fuzzy-PID controller for the VAV system is described importantly. The structure of the fusion type controller is given an the fuzzy logic rule set is shown. The simulation system for room temperature control using the designed controller is established by MATLAB. And the simulation result is given when different PID parameters are set. The simulation result proves the design is feasible.
