Vertical rotor for the implementation of control laws

IFAC Proceedings Volumes, 2012
Abstract This work presents a new laboratory educational device with which both undergraduates and postgraduates may visualize and test classic control laws and fuzzy logic controllers. A platform can move up and down impelled by a propeller attached to an electric motor.

Horizontal-Vertical-Rocking Coupled Response Analysis of Vertical Seismic Isolated Structure under Near-Fault Earthquakes

Shock and Vibration, 2020
For vertical isolated structures with excessive vertical eccentricity for mass and vertical stiffness, horizontal-vertical-rocking response needs to be better understood for vertical isolated structures located in near-fault areas, where long-period ...

Control of the vertical instability in tokamaks [PDF]

Nuclear Fusion, 1990
The problem of control of the vertical instability is studied for a massless filamentary plasma with finite resistivity included for the shell and active control coil. Stability boundaries are determined. The system can be stabilized up to a critical decay index, which is predominantly a function of the geometry of the passive stabilizing shell.

Vertical Control and Parallel Trade under Asymmetric Information

International Journal of Engineering Business Management, 2015
Parallel trade (PT) is a practice related to arbitrage operations in international trade. We provide a rationale for PT as an opportunistic behaviour by an international wholesaler who is privately informed about market demands in two countries where a ...
