A worst case identification method using time series data
In this paper we formulate and solve a control-oriented system identification problem for single-input, single-output, linear, shift-invariant, distributed parameter plants. In this problem the available a pri...

Finite-dimensional filters with nonlinear drift, VI: Linear structure of Ω
Ever since the concept of estimation algebra was first introduced by Brockett and Mitter independently, it has been playing a crucial role in the investigation of finite-dimensional nonlinear filters. Research...

Uncertainty Modelling and Robust Fault Diagnosis for Dynamic Systems
In earlier chapters of this book, we have seen that model-based FDI methods formally require a high accuracy mathematic model of the monitored system. The better the model is as a representation of the dynamic...

A Study on Fault-Tolerant Integrated Navigation Systems
In this chapter, navigation systems that comprise onboard inertial measurements with external aids, such as Global Positioning System (GPS) or Doppler radar, are considered. The objective of such systems is to...

Tracking performance with finite input energy
This paper studies an optimal control problem which is to minimize jointly the error in tracking a step reference and the energy of the plant input. We derive an analytical expression for the best attainable p...

Systems with Commensurate Delays
Stability criteria based on a frequency domain representation are time-honored tools in the study of dynamical systems. Classical examples of frequency domain stability criteria include such results as the Nyq...

Chapter
Robust Stability Analysis
In the previous chapters the stability property of a given time-delay system was studied. In engineering applications, it is now very common that one does not know exactly the system under investigation; that ...

Robust Stability Analysis
In this chapter we will discuss the robust stability problem of time-delay systems using the time-domain approach. The robust stability problem considers the stability problem of systems that contain some unce...

Chapter
Input-Output Stability
In this chapter we will discuss the input-output stability of time-delay systems. The main purpose of presenting this formulation is to consider the stability problem of systems under dynamical uncertainty. Th...

Chapter
Introduction to Time-Delay Systems
We begin this chapter by presenting a number of practical examples of time-delay systems. This should give the reader a glimpse into how widely time delays may occur in practice. To make the presentation more ...

Chapter
Systems with Incommensurate Delays
Unlike for those systems with commensurate delays, stability analysis for systems with incommensurate delays proves far more difficult. In particular, most of the results known to date are sufficient condition...

Chapter
Systems with Single Delay
In this chapter we will explore the time domain approaches of stability analysis. An advantage of time domain methods is the ease of handling nonlinearity and time-varying uncertainties. However, in order to i...

Chapter
Systems with Multiple and Distributed Delays
In this chapter we will discuss the stability and robust stability of systems with multiple delays and distributed delays using time domain methods. We will not treat specific uncertainty type and only give re...

A simplified NARMAX method using nonlinear input-output data
A system identification method for nonlinear systems with unknown structure is presented using short input-output data. The method simplifies the original NARMAX method. It introduces more general model struct...
