| 摘 要： | 维持控制点水位稳定是保证输水渠道安全有效运行的前提.以控制点水位偏差为主要抑制因子,基于线性二次型(LQR)指标,构建了渠道系统水位偏差、偏差变率和流量控制的全状态空间模型,将加入预测模块的线性二次型算法在渠道系统的全状态空间中进行分析和综合,提出了扰动可预知模型的构造方法.通过脉冲响应测试来加深对算法结构的理解,使用南水北调中线电子渠道平台对算法有效性进行验证,验证结果表明,该算法在渠道运行工况改变后,仍能够维持渠道的稳定运行,算法设计极具潜在的应用价值.

| Abstract: | Water level hold at specified locations within each reach is of the utmost importance for reliable and efficient management in a channel.A new algorithm for the control of unsteady flows in open channels is presented.An innovative control method is first analyzed,and then synthesized to construct a foreseeable module.The algorithm can thus be obtained by implanting the predicative module into a linear quadratic regulator(LQR).Using LQR,the canal operation problem can thus be reformulated as an optimal contr... |
