| First, the thesis depicts practical widely of fan-coil air-conditioning systems, their automatics development trends, then based on a great deal of literature, at home and abroad, combined with practice, proposes a design thinks that based on fuzzy control.Chapter two describes composing and characteristic of fan coil air conditioning system, stressed analysed characteristic and actuality of control system.Chapter three built all tache Math-model of fan coil air conditioning' s system , according as control flow of air conditioning system and practical engineering confirm parameter of room, fan coil unit, temperature sensor and so on.Chapter four describes first describes introduce design ways of elementary Fuzzy control controller. Then designed three ways of fuzzy controller, combined with characteristic, example that more disturb, great lay, nonlinear and time change.Chapter five aim at actuality in air conditioning control system, introduced development of system simulate technique and handle analysis-design software namely MATLAB/SIMULINK, which is fashioning in control field nowadays to design and analysis assistant building environment control system.After it introduced simply MATLAB language, SIMULINK system toolbox and fuzzy logical toolbox, this paper handle toolbox of MATLAB software built model. Simulated for controlled project, stressed to design' s process of fuzzy controller. Research three strategy controller effect fuzzy control that DISO fuzzy controller; DIDO fuzzy controller using three baddish of fan coil; fuzzy PID controller which combined with PID control and fuzzy control.Simulated result indicate that fuzzy control have agility in control, strong applicability, high precision and Robust characteristic. Specially suit for fan coil air conditioning system that complicated, hard to build model. It have comprehensive practical worth, and indicated that this method applying MATLAB/SIMULINK to analysis and design of air conditioning control system is...
