Abstract
Interest in increased flight safety, aircraft survivability, and performance improvements has led to significant advances in the design of adaptive fault tolerant (reconfigurable) control systems. However, there is a substantial gap between the researchand application of these methods. One reason is that most of the designs are not practical for use in existing aircraft because they require a complete redesign of the software (control system) and, in some cases, additional hardware (sensors, flightcomputers, etc.). The proposed work addresses many of the challenges associated with upgrading a production flight control system to improve capabilities of current Navy fleet aircraft. Reconfiguration is accomplished by computing increments to thepilot's commands that remove unwanted motions during maneuvering with control surface failures, battle damage, and mechanical, electrical, or hydraulic problems. This add-on (retrofit) control system is unobtrusive - i.e., it only generates nonzeroreconfiguration commands when the aircraft is responding unexpectedly. Another key advantage of the approach is that the command limiting, structural filters, and safety logic of the production control system remain in effect. This lessens certificationrequirements compared to other reconfigurable control methods. Phase II will advance the technology through algorithm and software development, hardware implementation, and F/A-18 flight testing.
