The invention provides an anti-saturation control method and device for an aviation propulsion system test bed, and relates to the technical field of anti-saturation control, and the method specifically comprises the steps: obtaining an opening instruction of a first control valve and an opening instruction of a second control valve at the current moment from a pre-established anti-saturation controller; the signals are respectively input to a first control valve and a second control valve; calculating the difference between the expected pressure value of the cavity at the current moment and the actual pressure value of the cavity at the previous moment to obtain a first error; calculating the difference between the expected temperature value of the cavity at the current moment and the actual temperature value of the cavity at the previous moment to obtain a second error; the anti-saturation controller is used for processing the first error and the second error, and opening degree instructions of the first co
