Studies on Fuzzy-neuro Immune Self-adaptive PID Controller for Constant Tension Control System

摘要: 应用免疫反馈系统原理和模糊神经网络控制理论,在传统PID控制基础上设计出一种模糊神经免疫自适应PID控制器,阐述了该控制器的特点、控制规律和整定方法.控制器参数P、I和D分别由模糊神经免疫反馈系统和模糊神经网络控制器在线修正.进行了恒张力控制系统的动态仿真,并与数字PID和模糊PID控制进行了比较.仿真结果表明,模糊神经免疫自适应PID控制器响应速度快、控制输出稳定、抗干扰能力强和鲁棒性好,较传统PID和模糊PID控制器具有更好的动、静态特性.

Abstract: A kind of fuzzy-neuro immune self-adaptive PID controller was designed based on the principium of immune feedback system,the theory of fuzzy neural network control as its main features,such as the characteristics,the control law,the control method were described.In this system parameter P is adaptively modulated by means of fuzzy-neuro immune feedback system,parameters I and D are dynamically regulated by fuzzy neural network controller.Simulation on constant tension control system was carried o...
