摘　　要：利用模糊技术的非线性特点和生物系统的免疫反馈原理,提出基于模糊免疫的PID控制器,该控制器根据控制量的变化自适应调整比例系数。仿真结果表明,该控制器具有良好的跟踪输入能力和满意的控制效果。目前,该算法已经成功应用于某造纸厂的漂白工段,一定程度上提高了漂白后的纸浆质量,取得了较好的经济效益。The fuzzy immunity PID controller is put forward in paper based on the nonlinear of fuzzy technology and immunity feedback principle of biological system, the controller adjusts the proportional coefficient according to variation of control output. The simulation results proves the controller has a good control effect and enhances control quality of process. Now, this controller has been applied to bleaching process in paper plant, improving the pulp quality and gaining good economical benefit.
