Interval State Estimation for Uncertain Nonlinear Systems
The objective of this work is to develop some design methods of interval observers for a class of nonlinear continuous-time systems. It is assumed that the estimated system can be represented as a superposition of the nominal subsystem (belonged to the class of uniformly observable systems) and a Lipschitz nonlinear perturbation vanishing at the origin. Then it is shown there exists an interval...
متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Interval estimation for uncertain systems with time-varying delays
The estimation problem for uncertain time-delay systems is addressed. A design method of reduced-order interval observers is proposed. The observer estimates the set of admissible values (the interval) for the state at each instant of time. The cases of known fixed delays and uncertain time-varying delays are analyzed. The proposed approach can be applied to linear delay systems and nonlinear t...
متن کاملH2/H∞ Multiobjectives for Fault Detection in Uncertain Polytopic Systems ⋆
Abstract: This paper presents a novel technique for robust fault detection, based on a modified H2/H∞ performance condition, which is described as LMI. Some theoretical results are shown in order to synthesize the residual generation scheme, for systems subjected to parametric uncertainty. The uncertainty parameters are supposed to belong to a polytope. The extended H2/H∞ conditions are obtaine...
متن کاملGeneral polynomial parameter-dependent Lyapunov functions for polytopic uncertain systems
New LMI conditions are given for robust H2 analysis of polytopic systems based on polynomial parameter-dependent Lyapunov functions. Results are derived using a ”slack variables” approach. Numerical results illustrate the characteristics of the proposed results in terms of conservatism reduction and numerical complexity.
