An　intelligent　control　scheme　for　fan　coil　air-conditioning　systems　has　been　put　forward　in　order　to　overcome　the　shortcomings　of　the　traditional　proportion-integral-derivative　(PID)　control　scheme.　These　shortcomings　include　the　inability　of　anti-interference　and　large　inertia.　An　intelligent　control　test　rig　of　fan　coil　air-conditioning　system　has　been　built,　and　MATLAB/Simulink　dynamics　simulation　software　has　been　adopted　to　implement　the　intelligent　control　scheme.　A　software　for　data　exchange　has　been　developed　to　combine　the　intelligence　control　system　and　the　building　automation　(BA)　system.　Experimental　tests　have　been　conducted　to　investigate　the　effectiveness　of　different　control　schemes　including　the　traditional　PID　control,　fuzzy　control,　and　fuzzy-PID　control　for　fan　coil　air-conditioning　system.　The　effects　of　control　schemes　have　been　compared　and　analyzed　in　robustness,　static　and　dynamic　character,　and　economy.　The　results　have　shown　that　the　developed　data　exchange　interface　software　can　induce　the　intelligent　control　scheme　of　the　BA　system　more　effectively.　Among　the　proposed　control　strategies,　fuzzy-PID　control　scheme　which　has　the　advantages　of　both　traditional　PID　and　fuzzy　schemes　is　the　optimal　control　scheme　for　the　fan　coil　air-conditioning　system.
