The Intelligent Control Department of the Information Science & Technology Division at the Applied Research Laboratory (ARL), researches and develops innovative control mechanisms, strategies and related technologies for non-traditional, distributed, and highly nonlinear systems. Intelligent control is multidisciplinary, incorporating research in software engineering, formal control theory, formal language theory, information and complexity theory, and signal analysis. Applications include computational languages for distributed autonomous control of robotic devices or nanoparticles, behavior discovery for situation awareness and control adaptation, and multiobjective mission planning for dynamic undersea scenarios. The Intelligent Control Department is able to combine internal resources with resources across the ARL and Penn State University to form multi-disciplined research and engineering teams supporting a wide range of programs. |
Key Areas of Expertise:
The Intelligent Control Department is committed to the advancement of distributed control and sensing technology through applied research, knowledge base development, studies and analyses. The Department has performed work for Department of Defense sponsors such as DARPA, ONR, and ARO. The Department has special expertise in heterogeneous systems operating in complex time-critical mission scenarios such as unmanned undersea vehicles (UUVs) and remote distributed sensor networks. Distributed, hierarchical control strategies allow collections of vehicles to self-organize into hierarchical teams capable of both coordinated collective behavior and robust autonomous activity. A language has been developed, called the Command Control & Communications Language (C3L), facilitating command and control-oriented communication among distributed autonomous systems. C3L also gives human mission planners the ability to script missions, command vehicles, and share behaviors. An intelligent controller architecture, the SAMON architecture, has been developed for UUVs and is being extended into other operational platforms such as unmanned aerial vehicles (UAVs) and industrial process control. The Department explores other forms of coordination as well such as semi-selfish multiagent cooperation. Often, in real-world scenarios, it is not possible for a central authority to have enough knowledge of the system to make proper control decisions. The semi-selfish control mechanism allows agents to make non-optimum local decisions in the form of peer-to-peer negotiation, which result in an emergent optimum global solution. In most cases, it would not have been possible to program the solution that emerges naturally from such a system. Essential to intelligent control is the ability to sense and interpret the environment. In this area, the Department has developed methods to convert data streams from distributed sensor platforms to symbolic strings that can be compared to previous readings and exemplars for classification and semantic description. Work in this area includes video understanding, target tracking, and threat analysis. Extension of this work into the nanotechnology arena facilitates data acquisition and analysis from nanosensor grids acting as “artificial noses” in detecting toxic and hazardous substances. The Department has also developed adaptive distributed sensor networks involving re-configuration of, and collaborative sensor fusion from, diverse networked sensing elements and technologies.
