| 中文摘要: |
| 采用模型预测控制算法研究多渠段中央集中控制。以渠道过渡过程的状态空间离散方程为基础，运用模型预测控制算法，构造目标方程，采用二次规划法求最优解。建立三渠池串联实验渠道及预测控制模型。分析其运行特性和时域特性，采用Matlab编程对5种初始条件下渠道运行状况进行仿真。结果表明：水流在各种复杂工况下均能快速、平顺地达到稳定，较好地解决了渠道运行中存在的耦合、大滞后问题，系统动态性能和鲁棒性优良。 |
| 英文摘要: |
| The formulation of controller for centralized control of canals applying the methodology of predictive control is presented. The formulation is based on the discrete linear state space model derived from Saint-Venant Equations with finite-difference scheme. The objective function is formulated as a quadratic programming problem to compute the control action. The application of the proposed control system to a 3-pool canal is numerically simulated. The software Matlab is adopted for computation programming. The simulation result shows that the model predictive control algorithm is successfully applied to the control of this multiple pools system. |
