复合光物理治疗仪体表温度模糊控制系统

Fuzzy control system of body surface temperature in physiotherapy system of compound light

本文首先介绍了复合光物理治疗仪的硬件组成原理,然后针对人体这一复杂的特大系统,应用Matlab模糊逻辑工具箱设计了以人体体表温度为被控对象的一种模糊控制方案。通过对被控对象的参数或结构发生变化时的仿真分析,得出该模糊控制器能够保持响应的快速性以及无静差、无超调的优良性能,具有很好的鲁棒性和适应性。

This paper introduces the hardware elements of the physiotherapy system of compound light firstly. Making use of fuzzy logic toolbox of Matlab, this paper then designs a fuzzy control algorithm of body surface temperature during therapy. A simulation research on controlled object whose parameters or structure are changed is done. It is shown that the fuzzy controller can keep the celerity of response, nicer performance of zero steadystate error and no over-shoot, the favorable robustness and adaptability.
