【摘要】 PID控制器是供热站循环泵控制中应用最为广泛的控制器,具有结构简单,适应性强等优点。但是其控制参数的调节始终是一个困扰人多年的重要问题。仿流水算法是一种启发式算法,利用自然界水流动的过程中所产生的现象,对PID参数进行调整和优化设计。设计利用连续型仿流水算法求得最佳的PID控制器参数值,使被控系统的输出相应达到最佳。更多还原

【Abstract】 PID controller is the most widely used controller in the control of circulating pump in heating station. It has the advantages of simple structure,strong adaptability and so on. But the adjustment of the control parameters is always an important problem for many years. The water flow-like algorithm is a heuristic algorithm,it uses the phenomenons which appear during the water flow in the natural to adjusted and optimize the parameters of PID controller. The continuous water flow-like algorithm is used to adjust parameters of PID controller,so that the output of the controlled system to achieve the best state.更多还原
