摘要
免疫响应反馈理论是维持生物体免疫平衡的关键,T细胞在不同的免疫阶段所具有的促进和抑制功能,保证了系统的快速响应和足够的稳定性。针对水轮机调节系统具有高度非线性、时变不确定、非最小相位等特点,通过免疫系统与控制系统的类比,借鉴免疫响应调节机理,利用免疫PID控制器来控制水轮机调节系统,并对该系统进行了仿真研究,仿真结果表明当工况变化和存在扰动时免疫PID控制器能有效的改善水轮机调节系统的动态性能,增强其鲁棒性和抗强干扰的能力。
The immune response feedback principle is an important method to maintain the immune balance inside organism, The function of T cells is both active and inhibitive, which provides immune system with fast response and adequate stabilization, Because of the nonlinear, time-varying and nominimum--phase characteristics of hydraulic turbine system. By comparing the control system and the immune system, an immune PID controller based on the immune system regulating law was used to control the hydraulic turbine system. Simulation analysis of the system was offered. The results show that the immune PID controller can improve the dynamic performance and strengthen the adaptive ability with fast response and strong robustness, especially, in the circumstance of foreign disturbance variation.
