The Direct Self-repairing Flight Control For Multiple Faults

The notion of Flight Self-Repairing Control was firstly brought forward by NASA in 1982. Our country began such research in!993. Direct Self-Repairing Control is a basic method proposed by paper [33] in 1999, which absent the time sequence of traditional repairing system , the repairing action would play its role at the moment the fault occurs without knowing failure modeling in advance. Thus the deficiencies accompanying the traditional self-repairing control law are avoided, which are long repairing time, bad control quality and low repairing ability. Consequently, the method becomes a very potential and spirited researching aspect.This article is based on paper [33]. It is the enrichment and development of Direct Self-Repairing theory. It mainly discusses the repairing action of direct self-repairing law brought forward in paper [33] for multiple failures occurring at the same time or in sequence. The problem of parameter selection in direct self-repairing law is also discussed. Then, the author do some theory analysis of the linearization problem of aircraft model equation and the modeling problem of buoy failure.From the view of theory , this paper strictly proves the effectivity of direct self-repairing law for most double faults. At last, the simulation results also support the conclusions in this article.
