Adaptive Controller Design for Faulty UAVs via Quantum Information Technology

International Journal of Advanced Robotic Systems, 2012
In this paper, an adaptive controller is designed for a UAV flight control system against faults and parametric uncertainties based on quantum information technology and the Popov hyperstability theory.

On the asymptotic hyperstability of switched systems

CoRR, 2013
Asymptotic hyperstability is achievable under certain switching laws if at least one of the feed-forward parameterization: 1) possesses a strictly positive real transfer function, 2) a minimum residence time interval is respected for each activation time interval of such a parameterization, and 3) a maximum allowable residence time interval is ...

Almost Multi-Cubic Mappings and a Fixed Point Application [PDF]

Sahand Communications in Mathematical Analysis, 2020
The aim of this paper is to introduce $n$-variables mappings which are cubic in each variable and to apply a fixed point theorem for the Hyers-Ulam stability of such mapping in non-Archimedean normed spaces.

Stability of the Fréchet Equation in Quasi-Banach Spaces

Mathematics, 2020
We investigate the Hyers–Ulam stability of the well-known Fréchet functional equation that comes from a characterization of inner product spaces. We also show its hyperstability on a restricted domain. We work in the framework of quasi-Banach spaces.

Application of hyperstability theory to interference cancelling [PDF]

, 1994
An alternative to the usual adaptive noise cancelling method devoted to removing interference is presented. In the conventional methodology to implement adaptive cancellers a reference signal is necessary correlated with the interference.

A Hyperstability/Multiobjective Optimization Approach for Active Flexible Structures

, 1991
A controller design method is proposed as a combination of the so-called hyperstability theory and the multiobjective optimization approach. In this combination the hyperstability theory serves to specify a computationally tractable controller stucture ...
