摘要： 本文考虑大坝—河流渠道灌溉系统的迭代学习控制问题。首先,对线性化的Hayami偏微分方程在空间上离散化,通过叠加向量方法建立闸门与流量关系的状态空间数学模型;其次,结合灌溉过程的重复性特点,设计D型迭代学习控制算法,建立了该算法的收敛性条件。结果表明通过闸门开度的迭代学习控制,可实现对取水口期望流量的完全跟踪。最后,通过数值仿真进一步说明提出的迭代学习控制方法的有效性。

Abstract: The iterative learning control problem of dam-river channel irrigation system is investigated in this paper. Firstly,the Hayami equation of the linearized equation is discretized in space,and the state space mathematical model of the relationship between gate and flow is established by superposition vector method. Secondly,based on the repetitive characteristics of irrigation process,a D-type iterative learning control algorithm is designed,and the convergence condition of the algorithm is also proposed. The results show that the iterative learning control of opening degree of the gate can make the actual output of the system completely track the expected flow rate in the channel. Finally,the validity of the proposed iterative learning control is illustrated by numerical simulation.

Key words: iterative learning control, irrigation system, Hayami equation, discretization
