Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0040] The working principle of the technical solution of the present invention: this technical solution obtains the phase characteristic of the closed-loop loop analytically and is used for the phase compensation of the stabilizer by establishing the analytical expression of the transfer function of the electromagnetic torque-speed loop in the incremental form. Link parameters are designed to accurately obtain the phase compensation angle required by the stabi...
