A hierarchical control approach for virtual coupling in metro trains
Comput. Aided Civ. Infrastructure Eng., 2023As an emerging technology, virtual coupling improves the efficiency and flexibility of metro services by forming multiple trains (units) as a virtually coupled train set (VCTS) without mechanical couplers.

Hierarchical Control With Voltage Balancing and Energy Management for Bipolar DC Microgrid
IEEE transactions on industrial electronics (1982. Print), 2023Bipolar dc microgrid (MG) based on two voltage levels with three wires has higher reliability and flexibility than unipolar dc MG. However, the voltages of bipolar buses are coupled and the voltage of the PN bus affects the voltages of the bipolar buses ...

A Hybrid AC/DC microgrid (MG) can integrate distributed generation sources and distributed loads on the AC and DC side of the MG by eliminating many unnecessary power conversion devices, which is more flexible and efficient.

In this article, the geometric adaptive robust hierarchical control strategy is proposed for underactuated quadrotor, in which the negative effects of nonlinearities, uncertainties, and coupling are thoroughly considered and effectively attenuated.

Hierarchical Fuzzy Controllers
IFAC Proceedings Volumes, 1995Abstract The paper presents Fuzzy Logic Controllers (FLC) with hierarchically structured rule base as nonlinear blocks used in a control system for direct control or supervision of standard controllers. Unified approach based on Fuzzy Logic Neural Networks (FLNN) is used to reveal the essential functions of a FLC.

Hierarchical control implementation
2007 Mediterranean Conference on Control & Automation, 2007The recently introduced concept of system abstraction appears to be a promising tool for control purposes in a hierarchical framework. While propagation of system's properties has been extensively studied, little investigation has been carried out on how a high-level control law is implemented on the low-level original system.

Hierarchical model predictive control
2007 46th IEEE Conference on Decision and Control, 2007This paper deals with the problem of designing stable hierarchical control schemes with Model Predictive Control (MPC). Specifically, at any layer of the considered structure, a robust MPC regulator is used to compute the control variables. In turn, these variables are produced by the subsystems at lower layers and must fulfill the robustness ...

Budgeting and Hierarchical Control
Journal of Accounting Research, 1997This paper develops a model of budgeting in hierarchical organizations. Each agent (manager) in the hierarchy receives a budget for a task. Based on his own information, the agent assigns tasks and budgets to his subordinates, who, in turn, do the same for their subordinates, and so forth.
