Stability region and radius in electric power systems under sustained random perturbations
(Elsevier, 2015)
Two concepts are proposed to characterize the behavior of stochastic systems under sustained random perturbations in time: Using Lyapunov exponents we define the region where an electric power system can be operated under ...
Closed loop stability of measure-driven impulsive control systems

Global stability analysis of a fractional differential system in hepatitis B
(2021-02-01)
This paper describes the dynamics of hepatitis B by a fractional-order model in the Caputo sense. The basic results of the fractional hepatitis B model are presented. Two equilibrium point for the model exists, the ...
Uniform Input-To-State Stability for Switched and Time-Varying Impulsive Systems
(Institute of Electrical and Electronics Engineers, 2020-12)
We provide a Lyapunov-function-based method for establishing different types of uniform input-to-state stability (ISS) for time-varying impulsive systems. The method generalizes to impulsive systems with inputs the well ...
An algorithm for computerized automatic tuning of power system stabilizers
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
The main objective of this paper is to relieve the power system engineers from the burden of the complex and time-consuming process of power system stabilizer (PSS) tuning. To achieve this goal, the paper proposes an ...
Transient stability improvement for electrical power systems based on the impedance change of a transmission system
(2020-06-01)
This study presents a new preventive control model based on sensitivity analysis that aims to improve the transient stability by changing the configuration of the transmission system. By considering a list of severe ...
Global Stability Results for Switched Systems Based on Weak Lyapunov Functions
(Institute of Electrical and Electronics Engineers, 2017-06)
In this paper we study the stability of nonlinear and time-varying switched systems under restricted switching. We approach the problem by decomposing the system dynamics into a nominal-like part and a perturbation-like ...
