International Conference on Control Applications &
IEEE International Symposium on Computer-Aided
Control Systems Design
September 25-27, 2000, Anchorage Hilton, Anchorage, Alaska, USA
Unmanned air vehicles are being used more and more in a number of civilian and military applications, e.g., remote monitoring of traffic, search and rescue operations, surveillance, etc. This has spanned considerable interest in the control community, mainly because the design of UAVs brings to light research questions falling in some of the most exciting "new directions" for automatic control. Examples of these are multi-agent coordination, probabilistic reasoning in control, vision in the feedback loop, sensor fusion, hybrid systems, biologically inspired systems, etc. Adding to this, many UAVs make use of new sensing and control technologies, such as Infrared Sensors (IR), Global Positioning System (GPS), Micro Electro Mechanical Systems (MEMS), etc.
In a one-day workshop, we cover a wide range of questions arising in the design of UAVs. This will be done systematically, starting with high-level mission planning and going all the way to single vehicle, integrated hardware/software design. The first set of talks address the coordination of fleets of UAVs. The specific questions covered include multi-agent pursuit-evasion games, conflict resolution, and hierarchical architectures for control and communication. A second set of talks concentrates navigation and sensing. In particular, on three-dimensional obstacle avoidance, the landing of UAVs on fixed or moving platforms, and the fusion of sensor data that includes GPS, INS, and vision measurements. The last set of talks focus on the design, modeling, and control of single UAVs. Special emphasis is put on the nonlinear nature of the systems. Biologically inspired design and hardware/software integration are also considered.
