Integrated fault tolerant control law

Abstract

This paper gives a progress report for developing an integrated, fault tolerant control law (IFTCL) which has capability for control reconfiguration and post stall maneuvering. To integrate these two technologies in an aircraft flight control system is attractive because in post stall conventional surfaces loose their effectiveness which resembles the aircraft in a conventional flight loosing its control surfaces due to battle damage or actuator failure. To develop such a control technique concurrent efforts were initiated. These efforts consisted of developing and evaluating control techniques for IFTCL, modifying a 6DOF high performance aircraft (HPA) model to have thrust vectoring capability, and laying out guidelines for developing a full-up, nonlinear control law (with transition logic) capable of continuously reconfiguring aircraft effecters for post stall maneuvers and reconfiguration due to battle damage and/or actuator failure.
