Stability Analysis of Nonlinear Time–Delayed Systems with Application to Biological Models

International Journal of Applied Mathematics and Computer Science, 2017
In this paper, we analyse the local stability of a gene-regulatory network and immunotherapy for cancer modelled as nonlinear time-delay systems. A numerically generated kernel, using the sum-of-squares decomposition of multivariate polynomials, is used ...

Eigen-Analysis Considering Time-Delay and Data-Loss of WAMS and ITS Application to WADC Design Based on Damping Torque Analysis

Energies, 2018
Data-loss from wide-area measurement systems (WAMS) is a stochastic event and eigenvalues of power systems containing data-loss cannot be calculated directly.

Electromagnetic torque analysis-based method for performance evaluation and optimisation of closed-loop CPS regarding small signal stability

IET Cyber-Physical Systems, 2018
Low frequency oscillation occurs frequently in the smart grid, which threatens the security and stability of the physical system. Wide-area damping controller (WADC), which belongs to cyber system, can effectively ...

Pest control using virus as control agent: A mathematical model

Nonlinear Analysis, 2012
It is now well recognised that biocontrol of pests is one of the best ecofriendly alternative for pest control. In this paper we have studied dynamical behaviours of a model for biocontrol of pests, where it is assumed that the pest is affected by a ...

Time Delays

, 2018
AbstractDelays often occur between an input into a system and the output from that system. Delays complicate dynamics, create system instabilities, and reduce the information that systems can use to respond to the environment. Adjusting for delays often requires systems to predict future states based on past inputs.

Reachable Set Estimation of Discrete Singular Systems with Time-Varying Delays and Bounded Peak Inputs

Mathematics
This paper studies the estimation of reachable sets for discrete-time singular systems with time-varying delays and bounded peak inputs. A novel linear matrix inequality condition for the reachable set estimation of the time-varying time-delay discrete ...
