Respirator pressure control adjusting method

The invention discloses a respirator pressure control adjusting method, which belongs to the technical field of medical equipment manufacturing, and comprises the following steps: in a pressure control mode, carrying out flow velocity estimation fuzzy control on inspiration pressure, monitoring the pressure change condition in a system by using a pressure sensor, calculating the control deviation of an exhalation valve, and carrying out PID control on the set inspiration pressure of the exhalation valve; the PID control parameters of the exhalation valve are subjected to grading fitting, the same feedback control time is adopted in the inspiration control algorithm and the exhalation control algorithm, the control effect is optimal under the same feedback control time, and the period control effect is fed back and controlled through bias adjustment of the PID control unit of the exhalation valve. According to the respirator pressure control and adjustment method, the problem of pressure rise caused after the
