CAOS: A hierarchical robot control system
Proceedings. 1987 IEEE International Conference on Robotics and Automation, 2005Control systems which enable robots to behave intelligently is a major issue in todays process of automating factories. This paper presents a hierarchical robot control system, termed CAOS for Control using Action Oriented Schemas, with ideas taken from the neurosciences.

Modeling and control of hierarchical systems with fuzzy systems
Automatica, 1996The paper proposes to use a fuzzy methodology to model the supervision and planning levels of a three level hierarchical control system. Only the first level of the process and the controller itself remain crisp. The main advantage of this system is that all levels of this hierarchical system can be formulated in a same mathematical framework.

Emulation/Simulation of Hierarchical Control Systems
IFAC Proceedings Volumes, 1983Abstract The concept of emulation/simulation as a means of computer-aided design of modular hierarchical hybrid control systems is described. An implementation of the concept has been developed and tested for an automated machining application.

Hierarchical control of discrete-event systems
Discrete Event Dynamic Systems, 1996An abstract hierarchical control theory is developed for discrete-event systems, based on the concepts of control structures and observers. The investigation is set in an elementary framework of formal languages constructed from the simplest principles of sets (languages) and order (lattices).

Hierarchical Control of Hybrid Systems
IFAC Proceedings Volumes, 1996Abstract The notion of dynamical consistency (Caines and Wei, 1995) is extended to hybrid systems so as to define the set of dynamically consistent hybrid partition machines associated with a continuous system S . After the presentation of some basic results on the algebraic structure of discrete partition machines, dynamical consistency is defined ...

Is growth controlled by a hierarchical system?
Zoological Journal of the Linnean Society, 1984A functional view of growth inevitably leads one to consider how it is controlled. There is much information on control mechanisms that regulate growth at different levels of organization within an organism. Some evidence is presented to establish that different types of control exist.

Hierarchical Control in the Motor System
IFAC Proceedings Volumes, 1977Summary The hierarchical structure of the sensory-motor system is studied, taking into account the multilayer and the multilevel concepts defined in hierarchical control. In particular, the experimental data on the eye-head system are considered, and some experimental guidelines for future experiments on the eye-hand system arc discussed.

Hierarchical control programs for systems evaluation
IBM Systems Journal, 1968Today's complex operating and computing systems make systems testing a difficult task. Major problems arise when one attempts to measure the performance of a system in a multiprogram environment and to evaluate the interfaces between computer elements, programs, and operator.

Hybrid Controllers for Hierarchically Decomposed Systems
2000We consider hybrid systems consisting of a lower-level component with time-driven dynamics interacting with a higher-level component with event-driven dynamics. These typically arise in manufacturing environments where the lower-level component represents physical processes and the higher-level component represents events related to these physical ...
