A method for controlling the converter comprises the steps of: receiving a reference flux (ψ*i) for the electrical converter; determining output signals (y) comprising currents and/or voltages measured in the filter; determining an estimated flux (ψi) from the output signals (y); determining a corrective flux (ψi,damp) from the output signals (y) based on a mathematical model of the filter and a quadratic cost function; determining control input signals (u) for the electrical converter based on a sum of the estimated flux (ψi) and the corrective flux (ψi,damp); controlling the converter with the control input signals (u); and algorithmic filtering of at least one of the output signals (y) by applying a signal filter to the at least one output signal, which is designed for amplifying the at least one output signal at a resonance frequency of the filter, whereby the corrective flux (ψi,damp) is determined from the filtered output signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control method for electrical converter with LC filter","description":"An electrical converter is interconnected via a filter with an electrical load or an electrical power source.
