要約(英語): Current control of three-phase AC motors with three-phase windings is generally performed via vector control. The basis of current control of motors with good characteristics entails obtaining a sinusoidal current with no ripple in steady state. However, in practice, current ripple often occurs due to inverter nonlinearity and other factors. Current ripple suppression is required to obtain the desired current response. This paper proposes a new current ripple suppression method using a D-matrix disturbance suppressor. The proposed disturbance suppressor has the following advantages. 1) It can be designed and implemented independently of the original current controller due to the structure of the two-degree-of-freedom control system. 2) It can selectively suppress current ripples based on the intensities of positive- and negative-phase current harmonics. 3) It has a high degree of freedom in configuration. 4) It is simple to design and implement.
