Abstract
We investigate fault recovery using reconfiguration for analog linear feedback control systems. We assume any faults occur only within the linear system and accessibility to its internal circuitry is impossible. Consequently, the only way to restore service - even degraded service - is by inserting a compensation network into the control loop. System failures are manifested by a change in the original bandwidth. The compensators are evolved intrinsically.
