{{Short description|Approach in control theory to achieve fault-tolerant control for dynamic systems}}
'''Control reconfiguration''' is an active approach in [[control theory]] to achieve [[Fault-Tolerant Control|fault-tolerant control]] for [[dynamic systems]].<ref>{{Harv|Blanke|Kinnaert|Lunze|Staroswiecki|2006}}</ref> It is used when severe [[Fault (technology)|faults]], such as actuator or sensor outages, cause a break-up of the [[control loop]], which must be restructured to prevent [[failure]] at the system level. In addition to loop restructuring, the [[Controller (control theory)|controller]] parameters must be adjusted to accommodate changed plant dynamics. Control reconfiguration is a building block toward increasing the [[dependability]] of systems under [[feedback]] control.<ref>{{Harv|Patton|1997}}</ref>

[[Image:FaultHiding with Goals.png|frame|Fault hiding principle. A reconfiguration block is placed between faulty plant and nominal controller. The
This paradigm aims at keeping the nominal controller in the loop. To this end, a reconfiguration block can be placed between the faulty plant and the nominal controller. Together with the faulty plant, it forms the reconfigured plant. The reconfiguration block has to fulfill the requirement that the behaviour of the reconfigured plant matches the behaviour of the nominal, that is fault-free plant.<ref>{{Harv|Steffen|2005}}</ref>
