RISOptimization of Cascade Pumping Stations’ Operations Based on Head Decomposition–Dynamic Programming Aggregation Method Considering Water Level Requirements
Publisher: American Society of Civil Engineers
Abstract: Aiming at the minimum power consumption for water pumping in a cascade pumping station system, we established a complex nonlinear mathematical model by taking optimized lift head and blade angle (or speed) of pump units ...
Compositing Coexisting Attractors by Linear Augmentation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the composition of coexisting attractors is achieved through the control method of linear augmentation, which can also be considered as a new idea to generate multiscroll attractors. In order to prove the ...
