Literature Overview,this topic, and unfortunately a lot of incompatible terminology has been used. Several different definitions are used for the term “reconfiguration”, leading to approaches that cannot be reasonably compared to each other. This overview tries to mention all approaches that are relevant for control re

The system contains two tanks connected by a valve and filled by a pump. The goal is to maintain a constant outflow of the system, which requires a constant level in

General Reconfiguration Problem,are many different ways to formulate the problem (several common approaches are listed in Patton [1997]). The problem formulation developed here is special for two reasons. On the one hand, it is kept as simple as possible. Only the minimal number of signals is used, and the definition is kept stric

Reconfiguration Using a Virtual Sensor,the 1970s when it has been studied in the context of fault detection as “dedicated (and generalised) observer scheme” (see Schröder [2003] for a modern version of this idea). However, in the literature the observer has only been used in combination with state feedback, while a general dynamical cont

Reconfiguration Using a Virtual Actuator,into a signal useful for the remaining actuators of the faulty plant. As shown in Chap. 6, a statical reconfiguration block is generally not sufficient, and a dynamical reconfiguration block is necessary to solve this problem. The . for the reconfiguration after actuator faults is the dual approach

Reconfiguration by Disturbance Decoupling,external output of the reconfigured control loop match the output of the nominal control loop. The approach builds on the virtual actuator, designed in Chap. 8 to stabilise a plant after actuator faults. In contrast to the reconfiguration problems treated earlier, this goal does not lead to an equiv

In both cases, the structural approach to the disturbance decoupling problem has advantages over the classical approach. It is simple to implement, and i
