Amulti-models Approach of Saint-venant’s Equations: a Stability Study by Lmi
نویسندگان
چکیده
This paper deals with the stability study of Partial Differential nonlinear Equation (PDE) of Saint-Venant. The proposed approach is based on the Multi-Models concept which takes into account some Linear Time Invariant (LTI) models defined around a set of operating points. This method allows to describe the dynamic of this nonlinear system in infinite dimension over a wide operating range. A stability analysis of the nonlinear PDE of Saint-Venant is proposed both by the use of Linear Matrix Inequality (LMI) and an Internal Model Boundary Control (IMBC) structures. The method is applied both in simulations and real experimentations through a micro channel, illustrating thus the theoretical results developed in the paper.

New method for coupling 1D unsteady flow hydraulic models using RST equations
This paper is devoted to the presentation and evaluation of different alternatives to couple two 1D hydraulic models based on the Saint-Venant’s equations. This presentation is first giving a short description of the coupling platform we use for these tests, namely the PALM coupling platform developed by Cerfacs. Then, we present 2 classical methods for this coupling: 1-way and 2-way. The 2-way...
متن کاملSaint-Venant’s Principe of the Problem of the Cylinder
The Statement of Modified Saint-Venant’s Principle is suggested. The axisymmetrical deformation of the infinite circular cylinder loaded by an equilibrium system of forces on its near end is discussed and its formulation of Modified Saint-Venant’s Principle is established. It is evident that finding solutions of boundary-value problems is a precise and pertinent approach to establish Saint-Vena...
متن کاملAn optimisation approach for stability analysis and controller synthesis of linear hyperbolic systems
In this paper, we consider the problems of stability analysis and control synthesis for first-order hyperbolic linear Partial Differential Equations (PDEs) over a bounded interval with spatially varying coefficients. We propose Linear Matrix Inequalities (LMI) conditions for the stability and for the design of boundary and distributed control for the system. These conditions involve an infinite...
متن کاملZanaboni Theory and Saint-Venant’s Principle: Updated
Zanaboni Theory is mathematically analyzed in this paper. The conclusion is that Zanaboni Theorem is invalid and not a proof of SaintVenant’s Principle; Discrete Zanaboni Theorem and Zanaboni’s energy decay are inconsistent with Saint-Venant’s decay; the inconsistency, discussed here, between Zanaboni Theory and Saint-Venant’s Principle provides more proofs that Saint-Venant’s Principle is not ...
متن کاملThe Stability of an Irrigation Canal System
In this paper we examine the stability of an irrigation canal system. The system considered is a single reach of an irrigation canal which is derived from Saint-Venant’s equations. It is modelled as a system of nonlinear partial differential equations which is then linearized. The linearized system consists of hyperbolic partial differential equations. Both the control and observation operators...
