Document Type and Number:
WIPO Patent Application WO/2020/107693
Kind Code:
A1
Abstract:
The present application relates to an air-oxygen mixer pressure control method and apparatus, and a computer device and a storage medium. The method comprises: acquiring a pressure setting value and a current pressure value; according to the current pressure value and the pressure setting value, calculating a current pressure error; according to the current pressure error and a pre-set mixer pressure model, obtaining a feedforward signal and a feedback signal of an adaptive control algorithm; according to the adaptive control algorithm determined by the feedforward signal and the feedback signal and based on a Lyapunov stability theory, designing an adaptive control law; and according to the adaptive control law, adjusting a control quantity required to maintain the pressure of an air-oxygen mixer system. According to an adaptive control law obtained by means of an adaptive control algorithm designed based on a pre-set mixer pressure model, a control quantity required to maintain the pressure of an air-oxygen mixer system can be adjusted online, a feedforward signal of the algorithm can be used for eliminating system errors, and a feedback signal is used for keeping the system stable, and feedforward and feedback control functions can realize accurate control over the pressure of an air-oxygen mixer.
