This paper studies regulation control of networked Euler-Lagrange system with unknown parameters and various time delays. An adaptive controller is proposed based on graph theory, Lyapunov stability theory and frequency-domain analysis. A distingctive feature of this work is to address the regulation with uncertain parameters, coupling input and communication delays in a unified theoretical framework...
The numerical calculation method is based on unstructured mesh well adaptability to the complex boundary, and the FVM (Finite Volume Method) form good conservation to the convective term flux. This coupled model adopting Roe second-order upwind scheme of FVM numerical analyzed to shallow water equation, and successfully introduced mild slope equation with weakly nonlinear amplitude dispersion, using...
For the evolution of the coastal, suspended sediment transport is an important factor. A large amount of suspended sediments transported under the wave and current action in the radial sand ridge field of the South Yellow Sea. This article introduces a numerical model which has adaptability to the complex border and the FVM (Finite Volume Method) conservation character. The character of this model...
This article describes the effects of some factors on the tip clearance flow in axial linear turbine cascades. The measurements of the total pressure loss coefficient are made at the cascade outlets by using a five-hole probe at exit Mach numbers of 0.10, 0.14 and 0.19. At each exit Mach number, experiments are performed at the tip clearance heights of 1.0%, 1.5%, 2.0%, 2.5% and 3.0% of the blade...
