in this paper, a finite-time control scheme is presented for stabilization ofthe satellite chaotic attitude around its equilibrium point whenits attitude is confused by a disturbed torque. controllers and settling timeof stabilizaton are obtained, based on the lyapunov stability theoremand finite-time control scheme. this method is satisfied for any initial condition.numerical simulations are ...

In this paper, the stability problem for digital redesign of discrete-time switched systems using H∞ linear matrix inequality (LMI) is investigated. We propose switching time approach between controller work and failure, will limit system output within capacity. When fails, overall be unstable. Therefore, if not restored in a certain period time, exceed To solve problem, we law to determine sta...

Aiming at the problems of model uncertainties and other external interference in trajectory tracking control n-degree freedom manipulators, a non-singular terminal sliding mode controller with nonlinear disturbance observer (NDO–NTSMC) method is proposed. A (NDO) designed to forecast compensate system interference, gain make error achieve expected exponential convergence rate so that feedforwar...

In this paper, we are going to estimate the domain of attraction of tumor-free equilibrium points in a perturbed cancer tumor model describing the tumor-immune system competition dynamics. The proposed method is based on an optimization problem solution for a chosen Lyapunov function that can be casted in terms of Linear Matrix Inequalities constraint and Taylor expansion of nonlinear terms. We...

Business Process Redesign (BPR) projects are considered to be high risk due to their high management complexity, enterprisewide impact, and steep project cost. This paper describes a technique that should reduce that risk by developing a systematic process redesign method that we call Dynamic Process Modeling (DPM). It integrates customer-oriented process modeling with computerized visual proce...

A new direct method for the computation of Lyapunov quantities (Lyapunov values or coefficients, Poincare-Lyapunov constants, focus values) for the second-order dynamical system, permitting us to narrow the requirements on a smoothness of system, is obtained.
