| 摘 要： | 三容器液位控制系统具有典型的滞后特性,用常规的PID控制难以达到精确的控制效果.本文首先给出了该系统的数学模型, 并应用Smith预估补偿算法进行控制,最后在C Builder中进行了仿真.仿真结果表明Smith预估补偿控制与常规的PID控制相比,具有调节时间短、超调量小、鲁棒性好等优点.

| Abstract: | Three tank water control system has character of hysteresis,and it is difficult to realize the precise control effective by the traditional PID method.The present article offers firstly its mathematic model and then a kind of Smith predictor design algorithm is given based on the mathematic model.The experiment and the simulation results are given based on C Builder.It is shown by the experiment and the simulation that the proposed control scheme has the advantages of robustness and transient properties with small tuning time and overshoot and is superior to the routine PID controller. |
