Robust stabilization of MIMO systems in finite/fixed time [PDF]
International Journal of Robust and Nonlinear Control, 2015 SummaryThe control design problem for finite‐time and fixed‐time stabilizations of linear multi‐input system with nonlinear uncertainties and disturbances is considered. The control design algorithm based on block decomposition and implicit Lyapunov function technique is developed.

Sliding Mode Control for Chaotic Systems with Unknown Uncertainties [PDF]
International Journal of Industrial Electronics, Control and OptimizationObjective: In this article, time-varying chaotic systems with uncertainties, including external disturbances, are considered, and sliding mode control (SMC) is used to control such systems. To control these systems, an autonomous differential equation is

Fixed-Time Stability of the Hydraulic Turbine Governing System [PDF]
Mathematical Problems in Engineering, 2018 This paper studies the problem of fixed-time stability of hydraulic turbine governing system with the elastic water hammer nonlinear model. To control and improve the quality of hydraulic turbine governing system, a new fixed-time control strategy is proposed, which can stabilize the water turbine governing system within a fixed time. Compared with the

Improved fixed-time consensus of delayed nonlinear leader–follower multi-agent systems
Nonlinear AnalysisThis article aims to study the problem of fixed-time consensus for nonlinear leader–follower multi-agent systems (MASs) with time delay. Firstly, a new fixed-time stability lemma is derived, where the condition of inequality contains a time-delayed term.

Fixed-Time Stability, Uniform Strong Dissipativity, and Stability of Nonlinear Feedback Systems
MathematicsIn this paper, we develop new necessary and sufficient Lyapunov conditions for fixed-time stability that refine the classical fixed-time stability results presented in the literature by providing an optimized estimate of the settling time bound that is ...
