Lyapunov function

A survey on constructing Lyapunov functions for reaction-diffusion systems with delay and their application in biology

Motivated by some biological and ecological problems given by reaction-diffusion systems with delays and boundary conditions of Neumann type and knowing their associated Lyapunov functions for delay ordinary differential equations, we consider a method for determining their Lyapunov functions to establish the local/global stability.  The method is essentially based on adding integral terms to the corresponding Lyapunov function for ordinary differential equations.  The new approach is not general but it is applicable in a wide variety of delays reaction-diffusion models

Analysis of Lyapunovmatrices’application Methods for Optimization of Stationary Dynamic Systems

In this article there has been conducted analysis of Lyapunov matrix application in order to form control inputs under different dynamic systems’ optimization methods oriented by quadratic integral criterion. For this purpose, the methods of finding the Lyapunov matrix and optimization based on the Bellman functional equation with subsequent application of the Riccati equation, optimization taking into account the initial values of state variables, optimization based on the Bellman equation using linear matrix inequalities and Lyapunov equation are considered.
