免疫PID控制器在木材干燥控制系统中的应用研究

Study of Immune PID Controller in Wood Drying Control System

通过免疫系统与控制系统类比,借鉴免疫响应调节机理,提出免疫PID控制器的设计方法,并讨论了免疫PID控制器与传统PID的结合方式及其免疫参数在调节过程中的作用。对木材干燥系统进行了仿真研究,结果表明,当工况变化和存在扰动时,免疫PID控制器也能获得满意的效果。

Based on the contrast between control system and immune system, with immune response regulation mechanism as reference, an immune PID controller is proposed. The methods for combining immune PID controller and traditional PID and the function of immune parameters of PID controller in regulating process are discussed. Simulation study is made on the wood drying system and the result shows immune PID controller can still obtain satisfying result in spite of the change of operation conditions and the existence of disturbances.
