Objectives

We are developing theory and algorithms for model-based verification and synthesis of control protocols. This includes development of specifications for desired system behavior and methods for synthesizing control protocols to achieve the specification. Target areas that we are currently exploring include:

• Protocols for real-time, multi-agent, airborne communication networks, including air-to-air, air-to-ground and satellite-based communications
• Vehicle management systems, including embedded control protocols individual and integrated subsystems
• Decision-making, resource allocation and fault handling in unmanned, autonomous vehicles and mission systems
• Aircraft electric power distribution systems.
