An introduction to autonomous control systems

The functions, characteristics, and benefits of autonomous control are outlined. An overview of some relevant research literature in the field of intelligent and autonomous control is given together with references that outline research directions. An autonomous control functional architecture for future space vehicles that incorporates the concepts and characteristics described is presented. The controller is hierarchical, with an execution level (the lowest level), coordination level (middle level), and management and organization level (highest level). The general characteristics of the overall architecture, including those of the three levels, are explained, and an example to illustrate their functions is given. Mathematical models for autonomous systems, including ´logical´ discrete event system models, are discussed. Some recent results from the areas of planning and expert systems, machine learning, artificial neural networks, and the area restructurable controls are briefly outlined.<>
