Linear Reconfiguration Problem
In this chapter, the general reconfiguration problem is specialised by applying it to linear systems. The advantage is that the problem can be broken...

Structural Solutions to Disturbance Decoupling
This chapter develops a novel algorithm which solves the disturbance decoupling problem by repeatedly decoupling one output variable at a time. The...

Literature Overview
This chapter introduces the main literature relevant for the field of reconfi-guration. During the last decade, different communities have dealt with...

Reconfiguration Using a Virtual Actuator
This chapter develops the concept of a virtual actuator. The idea of a virtual actuator is to use the input signal meant for the nominal process and...

Introduction to Control Reconfiguration
Controlled technological systems are used in many fields. They provide essential services such as the regulation of water pressure, the control of...

Direct Reconfiguration Using a Static Block
This chapter employs a static reconfiguration block in order to solve the direct reconfiguration problem. It is shown that this approach gives...

Solvability of Disturbance Decoupling
The strong reconfiguration problem leads to a disturbance decoupling problem as stated in Sect. 10.4. There are known structural tests for the...

Running Example: the 2-Tank System
A simple system will be used as a running example throughout the manuscript. It serves to illustrate typical faults and the resulting reconfiguration...

Reconfiguration of a Helicopter Model
A two-degrees-of-freedom helicopter experiment (see Fig. 17.1) is used as a more complex reconfiguration example. As demonstrated by Lunze et al....
-
Conclusion
This chapter mentions the main results of the manuscript. The motivation was to find methods for autonomous control reconfiguration after faults....
-
Reconfiguration Using a Virtual Sensor
This chapter develops the concept of a virtual sensor: when a sensor is at fault, an observer is used to calculate a replacement value. This approach...

Structural Models
The goal of structural modelling is to define all signal paths in a system.1 So for every possible signal path, the structural model has to determine...

General Reconfiguration Problem
In this chapter, a formal definition of the reconfiguration problem is developed. While the general idea of reconfiguration may appear obvious, there...

Basic Structural Properties
It is possible to attribute properties to a system structure. These properties are called structural properties, and they hold for almost all systems...

Reconfiguration of the 3-Tank System
The 3-Tank experiment is shown in Fig. 16.1. It consists of three tanks, which are connected via the valves u2, u3 and u4. Pumps can bring water into...
-
Reconfiguration by Disturbance Decoupling
This chapter addresses the strong reconfiguration goal for plants after actuator faults. The objective is to find a reconfigured block that makes the...

A Structural Reconfiguration Algorithm for Actuator Faults
This chapter summarises the results from the previous three chapters, and shows how they can be used to analyse and solve the reconfiguration...
-
Reconfiguration with Set-Point Tracking
This chapter treats the weak reconfiguration problem: the output equilibrium of the plant (for the same input) has to be restored (see Sect. 5.3 for...

Study on the Judgment of Fatigue Damage Stages in Welds Based on Entropy Analysis
This study aims to explore the relationship between the weld fatigue stages and metal magnetic memory signals so as to address challenges in...

Effect of Pressure and Temperature on the Microstructure and Mechanical Properties of SiCp/6061Al Coating Using High-Pressure Cold Spray
The SiCp/Al composite coating was prepared by cold spraying technology to avoid the formation of brittle compound Al 4 C 3 at low temperature. Plastic...
