基于迭代学习控制的双容水箱液位控制

针对双容水箱普遍存在的容积延迟的问题,以及传统PID控制效果不理想的特点,提出了基于迭代学习控制的双容水箱液位控制的方法。设计了双容水箱的PID型迭代学习控制器,其中包括开环PID型迭代学习控制器和闭环PID型迭代学习控制器。仿真结果表明,经过多次学习后,双容水箱在开环迭代学习控制器和闭环迭代学习控制器的控制下,可以较好地跟踪期望轨迹,获得较高的控制精度,验证了迭代学习控制方法的有效性。

Iterative Learning Control for Liquid Level Tracking of Double-Tanks

According to the problem of capacious-lags in double-tanks,and the characteristics of unsatisfactory control effect of traditional PID,the liquid level control method for double-tanks based on iterative learning control is proposed.of double-tanks is designed,which includes the open loop PID-type iterative learning controller and the closed loop PID-type iterative learning controller.The simulation results show that after many times of iterative learning,the double-tanks output can better track on the desired trajectory to meet the expected control effect under the control of the open loop PID-type iterative learning controller and the closed loop PID-type iterative learning controller.And the simulation results are also given to illustrate the effectiveness of the proposed method.
