人工免疫控制器在二元精馏塔控制中的仿真研究

生物免疫系统是一种在复杂干扰和不确定性的环境中具有很强的鲁棒性和自适应性的控制系统。依据生物多抗原多抗体协调免疫机理,以文献11]中的双因子免疫控制器为基础,提出了抗体交叉免疫耦合控制策略,并以此为基础设计了MIMO人工免疫控制器。以典型的二元精馏塔为被控对象,给出了MIMO人工免疫控制器具体实现方法。用仿真方法研究了MIMO人工免疫控制器的控制效果,并与传统的优化PID控制器做了比较。结果表明这种MIMO人工免疫控制器较传统优化的PID控制器性能优越。

Simulative Research of Artificial Immune Controller in Binary Distillation Column

The biological immune system is one kind of control systems,which has very strong robustness and self-adapted ability in the complex disturbance and uncertain environment. Based on the biological immune mechanism of antigens and antibodies interacting and the two-cell immune controller in the literature, an immune control strategy of antibodies coupling was proposed. Two MIMO artificial immune controllers were designed respectively based on the immune control strategies. A specific scheme of the MIMO artificial immune controller of a typical binary distillation column was given. The control result of the MIMO controller was researched with the simulation method and compared with the traditional PID controller. The results indicate that the performances of MIMO immune controller are better than those of the PID controller.
