仿人智能在协调控制系统中的应用研究

Application of human simulated intelligent PID in coordinated control system

为了更好的对单元机组协调控制系统进行优化,对主汽压力进行平稳的控制,提升变负荷速率,本文尝试引入仿人智能PID来取代常规的PID来进行优化控制。本文先通过对单回路的经典主汽压力系统加入仿人智能PID控制策略,观察其与文献中调试的相当合适的常规PID效果的对比,结果显示其性能指标明显优于常规PID,然后将其运用到经典的两输入两输出协调控制系统中,同样与论文中的PID效果进行对比,显示其确有提升变负荷速率的效果,且控制品质良好。本文通过对比研究,验证了仿人智能PID在协调控制系统中调压调负荷的良好表现,反映了其在现场生产中的可行性。

In order to optimize the unit coordinated control system better and ensure the smooth control of the main steam pressure and promote load change rate, this paper tries to introduce the intelligent PID to replace the conventional PID to optimize control. This paper frst joined the human simulated intelligent control strategy through the classic PID main steam pressure control system of single loop, to observe the efect of PID and conventional literature in debugging quite suitable contrast, results show that its performance is better than conventional PID, and then we apply it to two input two output classic coordinated control system, also compared with the PID efect, the display does raise the load change rate efect, and good control quality. Through comparative research, this paper verifes the good performance of the human intelligence PID in the coordinated control system, and refects the feasibility of the simulation in ？eld production.
