Dynamic Modeling and Observer-Based Fixed-Time Backstepping Control for a Hypersonic Morphing Waverider

Applied Sciences
This paper proposes a fixed-time backstepping control method based on a disturbance observer for a hypersonic morphing waverider (HMW). Firstly, considering the disturbance of attitude channels, a dynamic model of a variable-span-wing HMW considering ...

Stabilities of one-dimensional stationary states of Bose-Einstein condensates

, 2008
We explore the dynamical stabilities of a quasi-one dimensional (1D) Bose-Einstein condensate (BEC) consisting of fixed $N$ atoms with time-independent external potential.

Decentralized Event-Triggering for Control of Nonlinear Systems

, 2014
This paper considers nonlinear systems with full state feedback, a central controller and distributed sensors not co-located with the central controller. We present a methodology for designing decentralized asynchronous event-triggers, which utilize only

Finite/Fixed-Time Homogeneous Stabilization of Infinite Dimensional Systems

IEEE Transactions on Automatic Control
Finite/fixed-time control design procedure is developed for an infinite dimensional system modeled by abstract evolution equation in a Hilbert space. It is based on solving certain operator equations and inequalities. For a class of PDE models, the corresponding equations/inequalities are shown to be algebraic and solvable in many cases.

Finite/Fixed-Time Stabilization of Linear Systems With State Quantization

IEEE Transactions on Automatic Control
This paper develops a homogeneity-based approach to finite/fixed-time stabilization of linear time-invariant (LTI) system with quantized measurements. A sufficient condition for finite/fixed-time stabilization of multi-input LTI system under states quantization is derived.
