摘要
基于内模控制的PID控制器,只有一个可调参数,且该参数直接与系统的闭环响应速度和回路的鲁棒性有关,克服了常规PID控制参数整定复杂的缺点,易于为工程技术人员所掌握。城市供水出水浊度过程是一个大惯性、大时滞、非线性、时变以及随机干扰多的难控对象。而把IMC-PID控制器应用在该对象上,仿真结果表明可以取得较理想的控制效果。
PID controller based on internal model control has only a single adjustable parameter related to the response speed robustness of the system. The MIC-PID controller can greatly improve the control results and be easy to control by the engineers and technicians. An application of the controller to turbidity control of the municipal water supply system is presented, which is a non-linear and time varying process with a large time constant and large dead time.
