摘要
基于一种双因子免疫非线性反馈模型,结合控制系统的特点,构造出一个双因子免疫控制器,并给出了它的结构形式.理论研究和仿真试验均表明具有该免疫控制器的系统能够无余差地跟踪恒定输入.本文还将该免疫控制系统与免疫PID控制系统进行了对比仿真研究,结果表明,本文提出的双因子免疫控制器在抗纯滞后、适应对象参数变化等方面均优于免疫PID控制器,且参数选择方便.
Based on a two-cell immune nonlinear feedback model and the characteristics of the control system, a two-cell artificial immune controller is designed, and its structure is given in this paper. Both theoretical research and simulation indicate that the system controlled with this immune controller can follow the invariable input without any error. Through simulations, the proposed immune control system is compared with the immune PID control system, and the simulation results show that the former is better than the latter in anti-delay, self-adaptation of object parameter change, etc. , and it is easy for the former to choose parameters.
