  • Patent number: 11944599
    Abstract: A method of extracting myricetin from Xanthoceras sorbifolia Bunge is provided. The method includes: step 1, baking obtaining Xanthoceras sorbifolia Bunge crude powder; step 2, mixing the crude powder with a counter-current extraction solution to perform a counter-current extraction to obtain a filtrate and a filter residue; step 3, mixing the filter residue with a solvent to obtain a first mixture, and heating the first mixture to reflux for extraction to obtain an extraction liquid; step 4, mixing the extraction liquid and the filtrate, and concentrating under reduced pressure to obtain a concentrated solution; and step 5, separating and eluting the concentrated solution to obtain an eluent, then drying the eluent to obtain the myricetin.

  • Publication number: 20210124315
    Abstract: Disclosed is a method for designing a PID controller, having a control model C ? ( s ) = K P ? ( 1 + K I S ? + K D ? S u ) , wherein KD=aKI, and u=b?, a and b are proportional coefficients, the control model is reset as C ? ( s ) = K P ? ( 1 + K I S ? + aK I ? S b ? ? ? ) , a transfer function of a controlled object in a control system is set as G ? ( s ) = K s 3 + ? 1 ? s 2 + ? 2 ? s .
