In the urban water supply system, the location and quantity of the pressure monitoring nodes play a significant role for the monitoring effect and the response warning of the pipe burst. However, most installation of pressure monitoring nodes are based on human experience, which cannot totally present the whole water supply system condition. In view of the unreasonable layout of pressure monitoring...
In this work, a new approach to design constrained distributed MPC is proposed for linear parameter varying (LPV) systems subject to saturating actuator and state delay. Polytopic type uncertainty and only one state delay are considered in this paper. The algorithm requires decomposing the whole system into M subsystems and solving M linear matrix inequality (LMI) optimization problems for each subsystem...
In this paper, an approach to design constrained distributed model predictive control (MPC) is proposed for the polytopic uncertain systems with input delays. The large-scale linear system we consider is decomposed into several subsystems with distributed control inputs. This allows us to design distributed MPC controller independently for each subsystem. An augmented polytopic uncertainty description...
This paper mainly studies the hourly water demand forecasting performances of water supply system in shanghai with LS-SVM. The teaching-learning-based optimization (TLBO) is adopted to adjust the hyper-parameters of least squares support vector machine (LS-SVM). To improve the forecast accuracy, An ameliorated TLBO algorithm called ATLBO is introduced. The experimental results show that the model...
The optimization of the oxygen content in flue gas has a great impact on the safe and economic operation of boiler combustion system. With the model of BP neural network, the optimization of the oxygen content in flue gas is operated based on PSO, while the optimization settings are different under different load segments. The efficiency of the algorithm is proved by validation results of historical...
Ash deposition on heat transfer surfaces still to be a significant problem in power plant utility boilers. The effective ways to deal with this problem are accuracy on-line monitoring of ash fouling and soot-blowing. In this paper, the on-line ash fouling monitoring dynamic models of coal-fired utility boiler's heat transfer surfaces are proposed. The fundamental principle of the models is dynamic...
