1. Introduction. Nuclear radiation is fatal to the human body, so remote operation equipment is an indispensable tool for nuclear facilities [1 – 3].Generally, due to the influence of nuclear radiation in nuclear facilities, various devices are placed in a closed environment, which has high requirements for radiation protection, dust, temperature, humidity, and pressure.
Målet med projektet er: at kortlægge mulighederne for øget regulerbarhed af decentrale værker. Der fokuseres i projektet på at kortlægge evnen til både op- og nedregulering og ''overlast muligheder''. Herunder medtages en vurdering af behov for yderligere tekniske installationer for at i møde komme en øget reguleringsevne.
Conventional distributed control has achieved a great deal of success in multi-parallel cascaded H-bridge (CHB) power supplies. However, conventional distributed controllers can have a seriously imbalanced output power due to a mismatch of the hardware or control parameters and form an unstable circulating current path between the CHB converters, which …
There are several strategies for using DC/DC converters in parallel. The most common strategies are the droop method [5-7] and the active current sharing method [8, 9].The droop method controls the output resistance of each …
The chapter deals with control of low-voltage microgrids with master-slave architecture, where distributed energy resources interface with the grid by means of conventional current-driven inverters (energy gateways, slave units), and a voltage-driven grid-interactive inverter (utility interface, master unit) governs the interaction between the utility and the …
1 Introduction. The rapid development of low-voltage DC (LVDC) and high-voltage DC (HVDC) systems is stimulating engineers and researchers to think of ways of interconnecting the two to realise the universal DC system for the future [1-3].The multi-terminal voltage sourced converter medium-voltage DC (VSC-MVDC) distribution network is the new …
From my basic understanding of DC motor master-slave control, the master feeds the slave speed to operate at and they then run together @ the same speed and current. Any good articles or urls to recommend to read up more on master-slave dc motor control? Also, do not understand why when I...

The verification system mainly consists of a 6-DoF collaborative robot, a force feedback master manipulator, a loosening verification end effector and an end effector holder, as shown in Fig. 1-(a).The collaborative robot adopts AUBO-i5 collaborative robot, which has a 5 kg workload and a maximum working radius of 886.5 mm, with a repeatable positioning accuracy of ±0.02 mm.
In this paper, we analyze one of the main drawbacks of droop control-based DC microgrid systems, and propose a novel control method to overcome this problem.
The climbot, assembled with three basic modules, was developed via a modular approach. Figure 1 exhibits that the basic modules include T-type and I-type joint modules and a gripper module. The revolute axis of the T-type joint module is perpendicular to the link axes; and the rotational axis of the I-type joint is collin-ear with the link axes.

The well-known droop control and master-slave control methods are two dominant coordinative control schemes for inverter interfacing parallel distributed energy resources (DERs) in islanded AC microgrids. However, both these two control methods have some drawbacks and inherent limitations in practical application. After analyzing their complementary strengths and …
DC microgrid clusters are effective solutions for integrating multiple autonomous subgrids at the same and different voltage levels. In such a system, global power management is an essential concern, but it is always degraded by system structures and line impedances of distributed generation units (DGUs). To solve this problem, a decentralized multilayer master …
Usually, a master–slave minimally invasive surgical (MIS) robot [] consists of a master control console and several slave robot manipulators, on the end of which different surgical instruments could be mounted.During robot-assisted minimally invasive surgery, the surgeon only needs to sit by the master console and performs different operation actions with …
