LMI-Based Control for Grid-Connected Converters With LCL Filters Under Uncertain Parameters (2014, methodology): “2279015 controllers are based on the design of PI controllers in a synchronous reference frame for three-phase systems [13], using filter-based strategies [14], [15] or multiloop strategies [16]–[18].”
Step-by-Step Controller Design for LCL-Type Grid-Connected Inverter with Capacitor–Current-Feedback Active-Damping (2014, methodology): “be determined easily using root-locus method [26], [29].”
Active Damping-Based Control for Grid-Connected $LCL$ -Filtered Inverter With Injected Grid Current Feedback Only (2014, neutral): “The filter-based AD is used in [10], [11], and [13], where a first-order or higher order filter is added in, cascaded with the current controller.”
Grid-Current-Feedback Active Damping for LCL Resonance in Grid-Connected Voltage-Source Converters (2016, methodology): “The former represents a sensor-less technique realized by plugging in a digital filter, which unfortunately, is sensitive to parameter uncertainties and variations [10].”
Filter-Based Active Damping of Voltage Source Converters With $LCL$ Filter (2011, result): “It is worth noting that, in practice, the resonance peak apeak is lower compared with that of Fig. 2 due to iron losses [44], [ 47 ].”
Minimal Invasive Equivalent Grid Impedance Estimation in Inductive–Resistive Power Networks Using Extended Kalman Filter (2014, background): “Even though no passive damping resistors are used to damp the LCL filter resonance, no active resonance damping is added to the proportional-integral-based current control to simplify the control design [29].”
Generalized Design of High Performance Shunt Active Power Filter With Output LCL Filter (2012, background): “The desired switching frequency can eventually be set, which according to [24], should be set at least two times of ωres, so as to provide sufficient harmonic attenuation around the switching frequency.”
A New Feedback Method for PR Current Control of LCL-Filter-Based Grid-Connected Inverter (2010, background): “However, systems incorporating LCL filters are of third order, and they require more complex current control strategies to maintain system stability and are more susceptible to interference caused by grid-voltage distortion [4]‐[ 7 ].”
