Dynamic inflow for practical applications
WebThe paper presents the design and the implementation of different advanced control strategies that are applied to a nonlinear model of a thermal unit. A data-driven grey-box identification approach provided the physically–meaningful nonlinear continuous-time model, which represents the benchmark exploited in this work. The control problem of this … WebPractical application of stream channel routing often require the specification of lateral inflows. The lateral inflow could be concentrated (tributary flow), or distributed along the channel (groundwater exfiltration or infiltration). A mass balance leads to: (∂Q/∂x) + (∂A/∂t) = qL Multiplying this equation by dQ/dA (or βV) leads to:
