Abstract: The present invention discloses a reactive power sharing method for parallel inverters based on virtual impedance and a dynamic droop coefficient. The virtual impedance is constructed through the parameter design of voltage and current double-closed loop controllers and a line impedance observer, to realize power decoupling. A dynamic droop coefficient is constructed to adjust the output voltage of a virtual synchronous generator adaptively, and the output reactive power of inverters is controlled indirectly to achieve reactive power sharing according to capacities. The present invention does not need a communication network between the inverters, and only needs the local variable information of each inverter, so that a microgrid has the function of “plug and play”.

Abstract: An adaptive critic control algorithm integrating knowledge transfer for a wastewater treatment process is provided. This algorithm is used to achieve precise tracking of the dissolved oxygen concentration to the set value during the wastewater treatment process. When realizing the optimal control of a wastewater treatment system with an unknown model, the direct control strategy in the conventional adaptive critic control (ACC) algorithm is often sensitive to system disturbances, which may lead to a sharp decline in control performance. The present invention takes both knowledge transfer and incremental control into consideration. First, the anti-interference performance is effectively improved by optimizing the control strategy of the conventional ACC algorithm into an incremental form. Second, by leveraging the historical operation data of the system, knowledge transfer is implemented among different control methods.

Abstract: The present application discloses use of FcgammaRIIB as an IgG transport receptor in mammary gland of mammals, and belongs to the field of biotechnology. FcgammaRIIB knockout mice and FcgammaRIIB knockout pigs are constructed, and the ratio of mammalian serum IgG to milk IgG in the FcgammaRIIB knockout mice is significantly increased, indicating a decrease in relative milk IgG concentration. Although mammalian serum IgG content is significantly increased in the FcgammaRIIB knockout pigs, IgG in colostrum of mammals is nearly undetectable. Therefore, the present application demonstrates for the first time that FcgammaRIIB serves as the receptor mediating transport of mammalian serum IgG across the mammary epithelial barrier into milk, which addresses a long-standing unresolved issue in the field of maternal passive immunity. Furthermore, the present application provides a new strategy for increasing colostrum IgG content, thereby enhancing early immunity and survival rate of newborn livestock.

Therefore, interference fit does not need to be performed between the two axial end portions of the inner cylinder and the shaft assembly, and the cooling flow path can be realized in the transmission mechanism, thereby reducing the machining precision of a corresponding component, and being further capable of simplifying an assembling process and shortening the assembling duration.
