Abstract	Barron Associates, Inc. continues to focus on developing approaches to improve autonomous flight safety. Recent and ongoing projects include Intelligent Control of Unmanned Air Vehicles (AFRL PRDA), Algorithms and Tools for Automatic Updating of Simulation Databases (AFFTC Ph II), and Idiosyncratic Computer Signature Identification (OSD Ph I). Barron Associates continues developing Real-Time Guidance Adaptation and Trajectory Reshaping Algorithms for Reusable Launch Vehicles (part of the AFRL Integrated Adaptive Guidance and Control program – IAG&C). Flight tests were conducted at General Dynamics’ facility in Buffalo (formerly Veridian) using the TIFS in-flight simulator aircraft to simulate a vehicle with the Dynamics of the X-40A; and the algorithms are currently being ported to Boeing’s X-37 HIL testbed. Barron Associates is currently completing pre-flight checkout of the Retrofit Reconfigurable Control for the F/18 (NAVAIR Ph III). This development involved porting parameter identification, receding-horizon control, and baseline F-18 control algorithms to the Navy’s Fleet-Support Flight Control Computer (FSFCC). Flight tests are scheduled for November, 2004. 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 Ph II) and Run-Time Verification and Validation for Flight Critical Systems (AFRL Ph I). The former is concerned with intelligent Monte-Carlo analysis of complex control laws with analytic and simulation-based margin generation and estimation; the latter 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.
