Abstract: A multi-loop switching control system for a doubly-fed wind turbine based on logic switch control. Output variables of the doubly-fed wind turbine may be used to form output feedback control channels. Each output feedback control channel may switch between a switch controller and a vector controller to form a multi-loop switching controller. When a power system associated with the doubly-fed wind turbine is subjected to a relatively large external disturbance, state variables and the output variables of the wind turbine deviate from an original balance point, and the output feedback control loops of the doubly-fed wind turbine are switched from the vector controller to the switch controller. Under control of the switch controller, the state variables and output variables return to a vicinity of the original balance point, and the output feedback control loops of the wind turbine are switched from the switch controller to the vector controller.

Abstract: The present invention discloses a saury Maillard peptide with antihyperuricemic activity and its preparation method and application, with the method comprising the following steps: mincing a saury, adding water, heating, agitating, adjusting a pH value to 4.2, separating by centrifugation, and collecting the precipitate; adding water, proteases and amino acids to the precipitate, adjusting a pH value to 7.0, hydrolyzing, adding a reducing sugar to cause a reaction, centrifuging and collecting a supernatant which is saury Maillard peptide; and spray drying the peptide liquid to obtain a dry powder. The method of the present invention realizes the continuous action of enzymolysis and Maillard reaction to prepare the Maillard peptide, not only simplifying the production process, shortening the production cycle, and reducing the production costs, but also significantly enhancing the antihyperuricemic activity of the produced Maillard peptide. Animal experiments in rats showed that the obtained Maillard peptide prepared by the method of the present invention could significantly decrease the level of serum uric acid in rats, and display certain protective effect in their kidney.
