Control of Flow Limitation in Flexible Tubes

On a Limitation in Networked Flow Control

The paper analyzes a continuous time flow control system, with flow of a general quantity from a source node to a sink node. The flow is one-directional, meaning that there is a saturation between the nodes that limits the flow to be positive and below a maximum. The controlled plant is located in the sink node and the controller is located in the source node. The plant and the controller are m...

Simultaneous Control of Active and Reactive Powers of Vanadium Redox Flow Battery Systems in Flexible Microgrids

This paper discusses the control of flexible microgrids, consisting of a Redox Flow Batteries (RFB) and a new power conditioning system (PCS) for the RFB. Considering the importance of energy storage, this study is essential in power systems that are developed cautiously. RFB is connected to power system by a DC/DC or DC/AC converter to produce a DC voltage. It is very important that this conve...

Flexible Power Electronic Transformer for Power Flow Control Applications

This paper proposes a Flexible Power Electronic Transformer (FPET) for the application in the micro-grids. The low frequency transformer is usually used at the Point of Common Coupling (PCC) to connect the low voltage grid and utility network to each other. The conventional 50Hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. In this pap...

Test of wave-speed theory of flow limitation in elastic tubes.

Simulation of Flexible Tubes in VR

We present a Virtual Reality application enabling interactive, physically correct simulation of tube-like flexible objects. Our objective was to describe flexible objects by a set of parameters (length, diameter and material constants) instead of rigid geometry (triangle meshes) and to give the user the possibility to add, delete and manipulate those flexible objects in a stereo projected envir...
