Description
Summary:In this paper the capabilities of the agriculture electric drive with rectangular shape of the phase current were analyzed, the level of pulsations of the electromagnetic torque in synchronous reluctance electric drives was found, the synthesis of the electric drive control system was considered, the characteristics of the electric drive under different control laws were compared. It is found that the use of high-speed current circuits (cutoff frequency = > 200 rad/s) can significantly suppress the level of pulsations of the electromagnetic torque. It is shown that the use of flexible positive current feedback in switching phase currents can be considered as an additional opportunity to improve the performance of the current control circuit, as well as in conjunction with the previous method for suppressing torque pulsations in both static and dynamic modes.
