Zusammenfassung:The invention belongs to the technical field of power electronic converters, and discloses a control method for improving the frequency response capability of a direct-drive motor system, and the method specifically comprises the steps: a grid-side converter employs a self-synchronization control method, reflects the fluctuation condition of the frequency of a power grid on the basis of stabilizing the DC voltage, and improves the frequency response capability of the direct-drive motor system; the voltage amplitude and frequency of a grid-connected port of the back-to-back grid-connected converter are generated; the machine side converter adopts a rotating speed priority control method, on one hand, high dynamic response adjustment of rotating speed, torque and power is achieved, on the other hand, dynamic characteristics of the direct current side are reflected to the machine side converter, and the direct current voltage fluctuation quantity and the direct current serve as correction quantities of rotating
