Abstract	Barron Associates, Inc. reported on a number of recent and ongoing controls projects. The Retrofit Reconfigurable Control for the F/18 (NAVAIR Ph III) has been implemented and evaluated in HIL simulations on the Navy’s Fleet-Support Flight Control Computer (FSFCC at Pax River. This controller uses parameter identification and receding-horizon control to compensate for failures. Flight tests are scheduled for June, but could take place as early as April. Barron Associates is also working on fault detection approaches for transport aircraft (Langley) and marine diesel engines (ONR). In the area of transport aircraft, Barron Associates is working with Lockheed, Ft. Worth to provide diagnostics and adaptive outer loop technology to their AIMSAFE project (NASA Langley). In an STTR with UVA and U. Wyoming, Barron Associates is working to develop active flow control hardware and control algorithms for synthetic jet actuators (AFOSR). With Boeing and the Air Force, Barron is developing adaptive guidance, control, and trajectory generation algorithms for the DARPA CAV. Two Navy controls applications include control of undersea vehicles with multiple, diverse effectors (NavSEA) and control of a supercavitating torpedo (ONR). Barron Associates also continues to conduct research and development into tools and methods for V&V of intelligent systems. Projects in this area include. Control-law Automated Evaluation through Simulation-based and Analytic Routines- CAESAR (NASA Langley), Real-Time Monitoring of Safety Margins (NASA Langley) and Run-Time Verification and Validation for Flight Critical Systems (AFRL). The former is concerned with intelligent Monte-Carlo analysis of complex control laws with analytic and simulation-based margin generation and estimation; the monitoring work is concerned with real-time margin estimation and flight test supervision, and the AFRL work is concerned with software “wrappers” that monitor the execution of flight-critical software and safely revert to an off-line validated system in the presence of software errors or unforeseen adverse algorithm behavior.
