A Joint Active Damping Strategy Based on LCL-Type Grid-Connected Inverters for Grid Current Feedback and PCC Voltage Unit Feedforward [PDF]

open access: goldSensors
The negative high-pass filter feedback of the grid current (NFGCF) can offer active damping for the LCL-type grid-connected inverter. Due to the control delay in digital control systems, this damping can cause the system to exhibit non-minimum phase ...

Quasi-Active Damping

open access: yesVolume 1: 22nd Biennial Conference on Mechanical Vibration and Noise, Parts A and B, 2009
This article introduces a new method of system design using semi-active dampers named quasi-active damping. This technique is the design of dynamical systems and controllers using multiple semi-active dampers such that, at any instant, the desired control force can always be achieved using a combination of the dampers.
