摘　　要：针对低阶或高阶对象 ,提出一种新颖的基于生物免疫系统反馈机理的通用控制器结构。该控制器包括一个基本的 P型免疫反馈控制器和一个增量模块 ,P型免疫反馈规律由模糊控制器自动调整。激光热疗法中组织温度控制的计算机仿真结果表明 ,该控制器的控制性能优于常规控制器。A new universal controller structure based on the immune feedback mechanism of biological immune systems was presented. The controller included a basic P type immune feedback controller and an incremental block. The P type immune feedback law was automatically tuned by a fuzzy controller. The controller structure is suitable to various low or high order plants.Computer simulation results, in the control of tissue temperature during laser hyperthermia, demonstrate that the control performance of the immune controller is superior to that of conventional controller.
