Hierarchical Control of Lymphocyte Survival
Science, 1996After an immune response, the body must eliminate the excess cells generated to fight the foreign invader. Recent work indicates that this removal occurs as a result of an intricate network of regulatory processes. In their Perspective, Boise and Thompson synthesize this new evidence for the control of lymphocyte number by proteases, Bcl-2-related ...

Hierarchical control of flexible robots
1999 European Control Conference (ECC), 1999A hierarchical control for flexible manipulators is presented in this paper. The equations of motion are derived using the miltibody system method. Exploiting the structure of the dynamic model, the control concept allows to combine any given joint level control for the gross motion of the manipulator with a decentralized linear control of the elastic ...

Adaptive hierarchical fuzzy controller
IEEE Transactions on Systems, Man, and Cybernetics, 1993A methodology for designing adaptive hierarchical fuzzy controllers is presented. In order to evaluate this concept, several suitable performance indices were developed and converted to linguistic fuzzy variables. Based on those variables, a supervisory fuzzy rule set was constructed and used to change the parameters of a hierarchical fuzzy controller ...

Hierarchical control for artificial hearts
Proceedings IEEE International Symposium on Bio-Informatics and Biomedical Engineering, 2002This paper describes a hierarchical control structure to regulate the operation of turbo-hydrodynamic heart assist devices. The goal of the controller is to provide performance that satisfies as many clinical constraints as possible, consistent with the amount and validity of hemodynamic measurements available.

Hierarchical Mobility Controlled by the Network
2002The majority of IP based existing mobility solutions have significant handover execution time and movement detection delay. In this article, we present NCHMIPv6 (Network Controlled Hierarchical Mobile Internet Protocol version 6), a management protocol for hierarchical mobility controlled by the network.

Real-time hierarchical control
IEEE Software, 1992A framework for developing hierarchical control systems consisting of layers that group transformation types, the tools to help implement the layers and validate timing properties, and the mechanisms for communicating among layers is discussed. The layered framework supports the design and implementation of control systems with both continuous and ...

The ral hierarchical control system
Proceedings. 1986 IEEE International Conference on Robotics and Automation, 1986A Hierarchical Control System with organizer, coordinator and hardware levels has been developed. A VAX-11/750 serves as the organizer. An LSI-11/23 equipped with FPF11 floating point processor is the basis of the coordinator. The original controller for a PUMA-600 robotic manipulator has been modified to serve as the hardware level.

Hierarchical control of weakly-coupled systems
Automatica, 1980Abstract The usual concept of weakly coupled systems is generalized to provide a definition in terms ot the decomposition used. The definition inciudes a measure of the strength ot the coupling. The main result of the paper is a local convergence result for natural decompositions (decompositions which exploit system structure) of systems which are ...

Hierarchical Control in Microgrid
2019It is required to utilize several control loops together to increase reliability and performance of microgrids. The current and voltage magnitudes, frequency and angle information, active and reactive power data provide the involved feedback for normal and island mode operations of microgrid.
