Flight Control Reconfiguration

Abstract

Research into fault-tolerant control is a very actual problem and attracts many investigators. Their proposed solutions have fallen into two categories: passive and active. In the passive category, the impaired aircraft continues to operate with the same controller; the effectiveness of the scheme depends upon the original control law’s possessing a considerable degree of robustness. The active category involves either an on-line re-design of the control law after failure has occurred and has been detected, or the selection of a new pre-computed control law. In this chapter, the active methods are considered.
