This　paper　presents　the　design　of　compound-light　physiotherapy　apparatuses　for　gastrointestinal　disease　treatment.　A　contactless　measuring　temperature　method　based　on　infrared　ray　has　been　adopted　in　this　paper,　and　designs　a　fuzzy　control　algorithm　of　body　surface　temperature.　The　result　demonstrated　that　the　fuzzy　controller　can　keep　the　celerity　of　response,　and　maintain　a　nice　performance　without　steady　state　error　and　over-shoot.　When　parameters　or　structure　are　changed,　the　robustness　and　adaptability　of　the　apparatuses　has　also　been　proved　that　it　will　be　favorable.　©　2011　IEEE.
