The organization is inherently object-oriented and the control and the knowledge are distributed throughout the hierarchy. The hierarchy provides a multi-resolutional distributed and overlapping representation of the system where each node of the hierarchy contains some level of mathematical description intelligence and local sub optimal control. Theoretical foundations of these intelligent controllers are presented in an axiomatic approach which mathematically describes the hierarchy its functionality and the control process. This approach also provides formal definitions for concepts such as abstraction summarizing and decomposition. 1. INTRODUCTION In recent years the incorporation of intelligence into control systems has been focused on two major approaches. One of these approaches organizes the intelligence in planning reasoning and control hierarchically. The other approach creates intelligent response through a union of stimulus-response controllers. Although each approach has certain advantages a deeper understanding of 80 INTELLIGENT AND AUTONOMOUS CONTROL planning and reasoning can be obtained from the hierarchical approach with greater ease 1 . Hierarchical organizations can also be classified by the method by which they have been generated. One very popular method is to explore the functionality of the system and to form the hierarchy based on the functional decomposition of the goals to be accomplished. In this chapter this type of hierarchy will be referred as the function-based hierarchy. The other method is based on the objects associated with the physical
