Interval Observers for Linear Systems with Time-Varying Delays
This paper considers linear observed systems with time-varying delays, where the state as well as the observation of the state is subject to delays. It is assumed that the delays are unknown but stay below a certain bound. Similar to the case of uncertainties in the systems parameters we aim to derive upper and lower estimates for the state of the system under consideration. A pair of estimator...
متن کاملRobust Interval Observers for Discrete–time Systems of Luenberger type*
For a family of discrete-time systems with input and output and uncertain terms, a new interval observer is designed. Its main feature is that it is composed of two copies of classical observers, whose corresponding error equations are in general not nonnegative. It is shown how this interval observer can be modified to cope with the presence of nonlinear terms and disturbances and how asymptot...
متن کاملObservers for linear time-varying systems
In a general sense, observation is the problem of finding estimates for the current values of a set of signals given the current and the past values of another set of signals, where both signal sets are interconnected by the action of a dynamical system. In the work of Luenberger [6, 7] a method is described how this can be done in the context of linear time-invariant control systems, where the...
متن کاملAdmissibility analysis for discrete-time singular systems with time-varying delays by adopting the state-space Takagi-Sugeno fuzzy model
This paper is pertained with the problem of admissibility analysis of uncertain discrete-time nonlinear singular systems by adopting the state-space Takagi-Sugeno fuzzy model with time-delays and norm-bounded parameter uncertainties. Lyapunov Krasovskii functionals are constructed to obtain delay-dependent stability condition in terms of linear matrix inequalities, which is dependent on the low...
متن کاملProportional - Integral Observers for Discrete time Systems ∗
This paper applies the proportional-integral (PI) observer in connection with LQG and LQG/LTR design for discrete time systems. Both the prediction and the filtering versions of the PI observer are considered. We show that a PI observer makes it possible to obtain time recovery, i.e., exact recovery for t → ∞, under mild conditions. It is shown that LQG/LTR design is a special case of the cheap...
