摘 要: 本文基于神经内分泌系统的整体调节机制,提出一种新颖的非线性优化智能控制器。该控制器由提呈单元、抗体控制单元、主控单元、优化单元和辨识单元组成。提呈单元根据免疫提呈机制对控制偏差进行动态处理,抗体控制单元通过调整控制实体的数量来消除控制偏差,主控单元调整提呈单元和抗体控制单元的控制作用,优化单元和辨识单元优化提呈单元和抗体控制单元的参数。仿真结果表明,相对于传统的PID控制,该智能控制器具有较好的控制性能。
关 键 词: 非线性控制;神经内分泌免疫;免疫提呈;智能控制器

Abstract: Based on the modulation mechanism of neuroendocrine-immune system, this paper presents a novel nonlinear optimized intelligent controller(NOIC). The NOIC is composed of a presentation unit(PU), an antibody control unit(ACU), a main control unit(MCU), an optimization unit(OU) and an identification unit(IU). PU can pretreat the real-time control error dynamically based on the mechanism of immune presentation, and the ACU can adjust the number of antibody controller entity(ACE) to eliminate control error. MCU is designed to regulate the control action of PU and ACU. And the OU and IU can optimize the parameters of the PU and ACU based on the genetic algorithm(GA). The simulation results demonstrate that the control performance of the NOIC is better than that of the conventional PID controller.
Key words: nonlinear control; neuroendocrine-immune; immune presentation; intelligent controller
