The invention provides a LVAD undifferentiated adaptive fuzzy PI control method based on non-invasive measurement. The method is characterized in that a left ventricular volume is first measured by anon-invasive measurement remote-measurement system EMKA, filtering processing is carried out by a low-pass filter, a pump power-flow look-up table is used to obtain a desired average pump flow reference value to estimate a desired average pump flow measurement value; further the average pump flow reference value is compared with the average pump flow measurement value to obtain a flow deviation value e, the flow deviation value (e) and a flow rate deviation rate (de/dt) are subjected to fuzzification to obtain the fuzzy amount E and EC, a fuzzification method is used, the change values delta kp and delta ki of an adaptive proportional coefficient and an integral coefficient are determined according to different fuzzy quantities E and EC; the flow deviation value (e), the change values delta kp and delta ki of the adaptive proportional coefficient and the integral coefficient are input to a controller for processing, and a current signal output by the PI controller directly controls theLVAD to achieve a required pump speed omega under different physiological conditions.
