Hierarchical fuzzy control

FUZZ-IEEE'99. 1999 IEEE International Fuzzy Systems. Conference Proceedings (Cat. No.99CH36315), 1999
In this paper, a simplified method for developing Takagi-Sugeno-Kang (TSK) style fuzzy controllers is described. The method takes advantage of developer's knowledge and understanding of the system being implemented. System attributes such as variable and nonlinearity independence are utilized to significantly reduce the required rule-base size when ...

Hierarchical agent control

Proceedings of the fifth international conference on Autonomous agents, 2001
The Hierarchical Agent Control Architecture (HAC) is a general toolkit for specifying an agent's behavior. HAC supports action abstraction, resource management, sensor integration, and is well suited to controlling large numbers of agents in dynamic environments. It relies on three hierarchies: action, sensor, and context. The action hierarchy controls

A Novel Energy-Coupling-Based Hierarchical Control Approach for Unmanned Quadrotor Transportation Systems

IEEE/ASME transactions on mechatronics, 2019
Cable-suspended transportation is an important way of transferring goods and materials by rotorcraft in complex and hazardous environments, where external disturbances, system uncertainties, and, especially, the underactuated characteristic bring great ...

Hierarchical fuzzy control

International Journal of Control, 1991
Abstract In a conventional rule based fuzzy control system, the rules are of the following form: if (condition) then (action), and all rules are essentially in a random order. The number of rules increases exponentially as the number of the system variables, on which the fuzzy rules are based, is increased.

Efficient Improvement of Photovoltaic-Battery Systems in Standalone DC Microgrids Using a Local Hierarchical Control for the Battery System

IEEE transactions on power electronics, 2019
The conventional control methods for the battery systems of photovoltaic (PV) battery systems in standalone dc microgrids are designed to stringently regulate the bus voltages at the maximum power points (MPP) of PV modules while the state of charge (SOC)

Hierarchical Control of Lymphocyte Survival

Science, 1996
After 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 ...

Decentralized model predictive hierarchical control strategy for islanded AC microgrids

Electric power systems research, 2019
This paper presents decentralized Model Predictive Control (MPC) based hierarchical control scheme with both primary and secondary level for an islanded AC microgrid to address power quality and unequal power sharing problems. The control scheme consists

Hierarchical control of DC microgrid with dynamical load power sharing

Applied Energy, 2019
The hierarchical control strategy is proposed for DC microgrid with distributed generators, energy storage systems and loads. In order to maintain power balance and smooth bus voltage fluctuation during system operation due to dynamic load and resource ...

PC-Based Hierarchical Manufacturing Cell Control

IFAC Proceedings Volumes, 1992
Abstract Robots in the industrial factory plant build the backbone for CIM, which is outlined to be the factory automation strategy of the future. In this paper a hierarchical manufacturing cell control system for robotic work cells is described. This approach bases on low cost personal computer hardware and consists of two different control systems,

Hierarchical Control in Microgrid

2019
It 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.
