Abstract	The Control Science Center at the Air Force Research Laboratory is focused on control related research in five areas: autonomous control of unmanned air vehicles, hypersonic vehicle dynamics and control, verification and validation of complex systems, aircraft thermal management, and precision airdrop. The UAV team recently completed flight testing of a cooperative navigation algorithm that uses multiple UAVs and unattended ground sensors to navigate without GPS using range only measurements. A research effort focused on flapping wing micro air vehicle control was recently completed. A method for controlling a tailless flapping wing micro air vehicle that enables four degree-of-freedom maneuverability to be achieved by using only two physical actuators was developed and demonstrated. The method works by independently varying the stroke-plane velocities of passively rotating wings, such that commanded cycle-averaged forces and moments can be produced. Air table and force balance experiments demonstrated that roll, yaw, and translational control is possible by using only two brushless DC motors. A 34 gram vehicle achieved lift-off and demonstrated feasibility. In the area of hypersonic vehicle control, the group is focusing on implementing an adaptive control law on the HiFIRE 6 test vehicle. This test vehicle is a cold-flow path scramjet aircraft that was designed to fly at Mach 6 after separation from a sounding rocket. In the area of verification and validation we are working to develop techniques for verifying correctness of human-automation generated mission plans. To date, we have developed a formal framework that models the execution of mission plans as a transition system and mission specifications as Linear Temporal Logic formulae. This framework has been used in the development of a multi-UAV VIP escort scenario that is suitable for human-in-the-loop testing. In the area thermal management we are focused on control and mission planning schemes that maximize aircraft thermal endurance and range. In the area of precision airdrop we are focused on the development of physics based algorithms that use near real-time wind field measurements for determination of air release points for unguided drogue/parachute systems. Methods for minimizing impact dispersions of multiple packages by staggering main chute deployment times and load ordering have been developed and show considerable promise.
