Iterative Solution of Piecewise Linear Systems [PDF]
SIAM Journal on Scientific Computing, 2008 The correct formulation of numerical models for free-surface hydrodynamics often requires the solution of special linear systems whose coefficient matrix is a piecewise constant function of the solution itself. In so doing one may prevent the development of unrealistic negative water depths.

A generalized approach for implicit time integration of piecewise linear/nonlinear systems
International Journal of Mechanical System Dynamics, 2021 A generalized solution scheme using implicit time integrators for piecewise linear and nonlinear systems is developed. The piecewise linear characteristic has been well‐discussed in previous studies, in which the original problem has been transformed ...

Identification of Piecewise Linear Models of Complex Dynamical Systems [PDF]
, 2011 The paper addresses the realization and identification problem or a subclass of piecewise-affine hybrid systems. The paper provides necessary and sufficient conditions for existence of a realization, a characterization of minimality, and an ...

Limit cycles of planar piecewise linear Hamiltonian differential systems with two or three zones
Electronic Journal of Qualitative Theory of Differential Equations, 2022 In this paper, we study the existence of limit cycles in continuous and discontinuous planar piecewise linear Hamiltonian differential system with two or three zones separated by straight lines and such that the linear systems that define the piecewise ...

Piecewise linear identification of non-linear systems [PDF]
International Journal of Control, 1987 Methods of identifying a series of piecewise linear models which approximate to a non-linear system over some operating range are investigated. Spatial linear models and models with signal-dependent parameters are considered.

Simultaneous occurrence of sliding and crossing limit cycles in piecewise linear planar vector fields [PDF]
, 2019 In the present study we consider planar piecewise linear vector fields with two zones separated by the straight line $x=0$. Our goal is to study the existence of simultaneous crossing and sliding limit cycles for such a class of vector fields.

Piecewise-linear and birational toggling [PDF]
, 2014 We define piecewise-linear and birational analogues of the toggle-involutions on order ideals of posets studied by Striker and Williams and use them to define corresponding analogues of rowmotion and promotion that share many of the properties of ...

Crossing limit cycles for piecewise linear differential centers separated by a reducible cubic curve
Electronic Journal of Qualitative Theory of Differential Equations, 2020 As for the general planar differential systems one of the main problems for the piecewise linear differential systems is to determine the existence and the maximum number of crossing limits cycles that these systems can exhibit.

Bifurcation Phenomena in Two-Dimensional Piecewise Smooth Discontinuous Maps [PDF]
, 2008 In recent years the theory of border collision bifurcations has been developed for piecewise smooth maps that are continuous across the border, and has been successfully applied to explain nonsmooth bifurcation phenomena in physical systems.
