    针对四容水箱控制系统,使用Simulink搭建系统模型,并应用状态反馈控制律对系统进行控制。重点讨论了状态反馈原理以及LQR控制器的设计方法,简单介绍了加权矩阵Q和R的选择方法。对于最优跟踪问题使用LQI方法控制液位高度跟踪设定值,通过在MATLAB上对系统进行仿真实验,证实了所设计的控制器具有较好的控制效果,说明使用状态反馈的方法设计控制器是有效可行的。 For the four-tank control system, Simulink is used to build the system model and the state feedback control law is used to control the system. The principle of state feedback and the design method of LQR controller are discussed. The selection method of weighted matrix Q and R is introduced. For the optimal tracking problem, the LQI method is used to control the liquid level height tracking set value. The simulation experiment is carried out on the MATLAB system. It is proved that the designed controller has better control effect, and the controller is designed by using the state feedback method. Is effective and feasible.
