基于免疫机制的模糊PID控制器设计

Design of Fuzzy PID Controller Based on Immune

针对惯性、迟滞系统，本文结合PID、模糊控制和生物免疫原理，设计了一种基于免疫机制的模糊PID控制器。该控制器既具有PID控制的广泛性，也具有模糊控制的非线性逼近作用，还具有免疫控制的自适应调节能力。借助MATLAB的模糊控制工具箱和simulink仿真工具进行验证，结果表明基于免疫机制的模糊PID控制的动态性能和稳态性能都优于PID控制和模糊PID控制。

To inertia and retardation system, a fuzzy PID controller based on immune was designed with PID, fuzzy control and biological immune principle. The controller not only had the universality of PID control, but also had the nonlinear approximation function of fuzzy control, and also had the adaptive control ability of immune control. With the help of MATLAB＇s fuzzy control toolbox and simulink simulation tool, the results showed that the dynamic perfor- mance and steady state performance of the fuzzy PID control based on the immune were superior to the PID and the fuzzy PID control.
