High order ADER schemes and GLM curl cleaning for a first order hyperbolic formulation of compressible flow with surface tension [PDF]

Journal of Computational Physics, 2020
In this work, we introduce two novel reformulations of a recent weakly hyperbolic model for two-phase flow with surface tension. In the model, the tracking of phase boundaries is achieved by using a vector interface field, rather than a scalar tracer, so

A survey of delay compensation and control based on continuum backstepping control algorithms for time-delay systems

工程科学学报, 2022
In practical control systems, time delays inevitably occur when sensors need to measure and require the system’s data for decision making as well as when microcontrollers (or other devices) compute and implement control signal processes.

On strong hyperbolicity for first order systems

Proceedings of the Japan Academy, Series A, Mathematical Sciences, 1985
The author studies the strong hyperbolicity for first order hyperbolic systems \[ L(x,D)=-D_ 0+\sum^{d}_{j=1}A_ j(x)D_ j+B(x) \] where \(A_ j(x)\), B(x) are \(N\times N\) matrices with smooth entries defined near the origin in \(R^{d+1}\) with coordinates \(x=(x_ 0,x^ 1)=(x_ 0,x_ 1,...,x_ d)\) and \(D_ j=-i(\partial /\partial x_ j)\).

Piecewise linear differential systems with an algebraic line of separation

Electronic Journal of Differential Equations, 2020
We study the number of limit cycles of planar piecewise linear differential systems separated by a branch of an algebraic curve. We show that for each $n\in\mathbb{N}$ there exist piecewise linear differential systems separated by an algebraic curve ...

Extended-State-Observer-Based Chattering Free Sliding Mode Control for Nonlinear Systems With Mismatched Disturbance

IEEE Access, 2018
This paper presents a novel chattering free sliding mode control method for a class of nonlinear systems in the presence of matched disturbance and mismatched disturbance based on an extended state observer.

Comparison of high-order methods on unstructured grids [PDF]

, 2013
A high-order Discontinuous Galerkin (DG) method is formulated and implemented on the Cranfield University’s 3D unstructured Finite Volume Method (FVM) code (UCNS3D), for both linear and non-linear hyperbolic conservation laws and for test-cases which ...
