Research on Compound-light Physiotherapy Apparatuses for Gastrointestinal Disease Treatment

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.
