Abstract
Using biological immune principle and fuzzy theory, this paper gives a design of a fuzzy immune self-adjusting PID controller based on the differences among general PID control algorithm, fuzzy self-adjusting PID control algorithm and immune PID control algorithm. This kind of controller is used in the research of the self-heating system successfully. This kind of controller has a simple structure. Its parameters are also convenient to be adjusted. This paper makes the simulation program using the m-file in Matlab. The simulation experiments show that the robustness and self-adaptive ability of the controller is better than those of general PID control algorithm, fuzzy self-adjusting PID control algorithm and immune PID control algorithm.
