为了研究泥沙在杭州运西河网内的沿程输移淤积规律,基于非均匀沙不平衡输移理论,结合黏性非均匀沙起动概率公式和非均匀沙水流挟沙能力公式,得到改进后的河网悬移质沿程含沙浓度计算公式。计算了杭州市从钱塘江引水至运西河网"四港四河"内的悬移质沿程含沙浓度及河网沿程淤积率。结果表明:河网引入钱塘江水后,河网内悬移质含沙浓度呈明显的沿程减小趋势。在引入流量相同时,河网淤积率随引入水体含沙浓度的增大而增大;当引入水体的含沙浓度相同时,河网淤积率随引入流量的增大而降低。研究结果可以为该区域河道清淤提供参考。

An iterative learning model predictive control （ILMPC） technique is applied to a class of continuous/batch processes. Such processes are characterized by the operations of batch processes generating periodic strong disturbances to the continuous processes and traditional regulatory controllers are unable to eliminate these periodic disturbances. ILMPC integrates the feature of iterative learning control （ILC） handling repetitive signal and the flexibility of model predictive control （MPC）. By on-line monitoring the operation status of batch processes, an event-driven iterative learning algorithm for batch repetitive disturbances is initiated and the soft constraints are adjusted timely as the feasible region is away from the desired operating zone. The results of an industrial application show that the proposed ILMPC method is effective for a class of continuous/batch processes.
