Application of A New Immune Controller in Main Steam Pressure Control System

基于生物免疫系统响应的快速性和稳定性,借鉴免疫调节过程中B、T细胞的作用原理,文中提出了一种新型的免疫控制器,并与常规比例积分微分(PID)控制器结合构成并联型的免疫PID控制器,以改善控制性能。该控制器结构简单,整定方便,易于工程实现。应用于主蒸汽压力的仿真结果表明,该控制器具有较好的跟踪性能、抗干扰能力和鲁棒性,能快速响应机组实发电功率指令的变化,有效地克服了锅炉燃烧率内扰的影响,改善了机组负荷的跟踪性能,提高了机组的运行经济性。

Based upon the quick acting and stability of bio-immune system response,and using The action principle of B cell and T cell in the immune regulation process,the paper presents a new type immune co.roller,which combining with the conventional PID. controller, constitutes a paralleling type immune PID controller to improve the control porformance. The configuration of this controller is simple,easy to tune,so it is easy to realize in project. The simulation for the main steam pressure show that this controller is of better tracking performance, better antijamming performance and robust performance,can rapidly response the modification of actual generation pov, er orders of traits,effectively overcome the influence of internal jamming of boiler combustion rate,thus improve the tracking performance of unit＇s load and operation economics of units.
