Control and coordination in hierarchical systems
European Journal of Operational Research, 1981This book presents the applied theory of control and cooordination in hierarchical systems which are those where decision making has been divided in a certain way. It concentrates on various aspects of optimal control in large scale systems and covers a range of topics from multilevel methods for optimizing by interactive feedback procedures to ...

About Hierarchical Control Systems Organization
IFAC Proceedings Volumes, 1982Abstract The hierarchical and decentralized approach to the control problem represents certain advantages over the centralized approach. The progress in the area of microprocessors accelarates the replacement of the conventional centralized analog control with distributed digital control systems.

Hierarchical Control in a Multiagent System
Second International Conference on Innovative Computing, Informatio and Control (ICICIC 2007), 2007The hierarchical decomposition approach as a pervasive method to deal with undesirable computation allows for reduced computation, and provides solutions for larger and more complicated problems. However, there is a necessity for research efforts towards the arrangement of local operational performance criteria to the overall performance of a whole ...

Hierarchical Control of Power Systems
IFAC Proceedings Volumes, 1977Abstract The control problem of power systems is influenced by the following factors. The control strategy objective, the type of disturbance a power system may be subjected to, the state it may be undergoing following a disturbance and the fact that the power system is physically formed of many interacting components with different designs and ...

Hierarchical feedback control system
Proceedings of 32nd IEEE Conference on Decision and Control, 2002This paper introduces an architecture that is based upon a concept of nested hierarchical (multiresolutional) control systems. Multiresolutional representation of control variables which allows for a hierarchical prediction of the next sample error vector.

Adaptive control of a Networked Control System with hierarchical scheduling
Proceedings of the 2011 American Control Conference, 2011In this paper, we consider a special class of Networked Control Systems (NCS) that occur in embedded systems where a hierarchical schedule is employed and uncertainties may be present either in the plant or in the network. An adaptive controller is proposed to accommodate the effect of uncertainties.

Hierarchical systems control using threshold fuzzy systems
2001 IEEE International Conference on Systems, Man and Cybernetics. e-Systems and e-Man for Cybernetics in Cyberspace (Cat.No.01CH37236), 2002This paper describes a behavior-based method of controlling an autonomous skid-steer robot operating in an unknown environment. We introduce a new modular, neural-fuzzy system called a threshold fuzzy system (TFS). Supervised training, using error backpropagation, is used to find optimal parameters of the TFS.

Hierarchical optimal control of redundant biomechanical systems
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005Sensorimotor control occurs simultaneously on multiple levels. We present a general approach to designing feedback control hierarchies for redundant biomechanical systems, that approximate the (non-hierarchical) optimal control law but have much lower computational demands.

Modular, hierarchical models of control systems in SpaceEx
2013 European Control Conference (ECC), 2013The Hybrid I/O-automaton (HIOA) is a rigorous formal model designed for the analysis of complex hybrid (discrete-continuous) dynamical systems. The use of the HIOA formalism renders compositional reasoning possible, in the sense that once a property has been established for an automaton, it still holds if the automaton is composed with other automata ...

Hierarchical distributed control for networked linear systems
53rd IEEE Conference on Decision and Control, 2014In this paper, we propose a design method of hierarchical distributed controllers for networked linear systems. The hierarchical distributed controller has an advantage that an L2-performance of the closed-loop system improves as improving a performance of local controllers that stabilize disjoint subsystems individually.
