Parameter Optimization of Virtual Impedance for Parallel Inverter

Advanced Materials Research, 2014
This paper deals with parameter optimization of virtual impedance of parallel inverter. Conventional design methods determine parameters by observing the changes of amplitude-frequency and phase frequency curves of the equivalent impedance. However, those methods always neglect the dynamic performance of inverters in parallel.

Virtual Impedance Control for Safe Human-Robot Interaction

Journal of Intelligent & Robotic Systems, 2015
Collision avoidance is essential for safe robot manipulation. Especially with humans around, robots should work only when safety can be robustly guaranteed. In this paper, we propose using virtual impedance control for reactive, smooth, and consistent collision avoidance that interferes minimally with the original task.

Virtual impedance attenuation based control of parallel inverters

2014 IEEE Conference and Expo Transportation Electrification Asia-Pacific (ITEC Asia-Pacific), 2014
Current sharing is a main problem in AC power supply system with multiple inverters parallel connected. Some methods are developed to eliminate the loop-current among inverters including droop control and virtual impedance. However, big voltage drop is inevitable for a good current sharing.

Fuzzy virtual impedance controller in human-vehicle interaction

2009 IEEE International Conference on Systems, Man and Cybernetics, 2009
In the previous studies mechanical impedance has become well implement in the field of human-machine interaction. However, in human-vehicle interaction there is a variant environment when driving a vehicle, thus apart from interacting with human, impedance controller is needed to adapt to the variant environment. But for mechanical impedance as being a

An improved droop control with tunable virtual impedance

2016 Chinese Control and Decision Conference (CCDC), 2016
A droop control with tunable virtual impedance based on the cloud model theory is proposed in the paper. Because of the imbalance feeder impedance in low voltage micro-grid, it is difficult for the traditional droop control to get good performance. The tunable virtual impedance is needed to conquer these problems due to the difficulty of getting the ...
