以生物免疫中T细胞和B细胞间的协同免疫机理为基础,结合多抗原多抗体协调免疫机理,提出一种分布式-多输入多输出耦合的人工免疫控制策略,并将该策略应用于直流蒸汽发生器(OTSG)压力控制。为了验证该控制策略,在1台快堆仿真系统中进行了仿真实验。仿真测试结果表明,该控制策略较比例、积分、微分(PID)控制具有更小的超调量和调整时间,能够有效改善OTSG压力和相关参数的动态运行特性。 Based on the mechanism of synergistic immunity between T cells and B cells in biological immunity and combined with the immune mechanism of multi-antigen polyclonal antibody, a distributed-multiple-input-multiple-output artificial immune control strategy is proposed and applied to DC Steam generator (OTSG) pressure control. In order to verify the control strategy, a simulation experiment was carried out in a fast reactor simulation system. Simulation results show that this control strategy has smaller overshoot and adjustment time than proportional, integral and derivative (PID) control, which can effectively improve the dynamic operating characteristics of OTSG pressure and related parameters.
