针对控制性能指标不兼容难以选择控制器,提出了一种改进的PSO控制算法.构造了基于多性能指标参数的目标函数,研究了基于PSO的改进控制算法,剖析了可快速搜索到收敛于全局最优极值所对应各个控制器控制参数机理,以SBR工艺污水处理系统控制器参数选择为例,建立了DO参数控制模型,设计了改进的PID控制器和多模态HSIC控制器.仿真实验显示:改进的PSO算法有更强的鲁棒性和更好的动静态控制品质.研究结果表明该算法用于污水处理系统控制器参数优选的合理性与可用性.
Aiming at the incompatible control performance index, it is difficult to choose the controller, and an improved PSO control algorithm is proposed.An objective function based on multi-performance index parameters is constructed, and an improved control algorithm based on PSO is studied, The optimal extreme value corresponding to each controller’s control parameter mechanism, taking the SBR process sewage treatment system controller parameter selection as an example, establishes the DO parameter control model, designs the improved PID controller and the multimodal HSIC controller. It shows that the improved PSO algorithm has stronger robustness and better dynamic and static control quality.The results show that the proposed algorithm is suitable for the reasonableness and usability of the controller parameters of the wastewater treatment system.
