摘要： A method for actuating a frequency converter (520) comprises steps for measuring phase currents (831, 832, 833) which flow in phase conductors (531, 532, 533) of a three-phase supply system (530), for generating a first modulation space vector (572) which has an angle (573) which is synchronous to a system voltage of the three-phrase supply system (530) and has a fixed modulation index (575) as amplitude, for generating a third modulation space vector (873) as a function of the first modulation space vector (572) and the measured phase currents (831, 832, 833), and for modulating the frequency converter (520) in accordance with the third modulation space vector (873).

摘要： A closed-loop control method with multi-channel feedback is described, in which a feedback variable r1, which is determined by sampling a closed-loop control variable x with a sampling frequency fA, and a further feedback variable r2, which is determined by averaging the closed-loop control variable x over a time period Ts, are each separately compared with a guide variable w. Each of the control errors e1, e1, which are determined in the process is fed to a separate controller 31, 32 which respectively forms therefrom an individual closed-loop control output variable m1, m2. Finally, a closed-loop control output variable m, formed from the individual closed-loop control output variables m1, m2, is used to adjust the closed-loop control variable x so that the closed-loop control variable x follows the guide variable w.
