The invention relates to an air entraining system for entraining air by using an auxiliary power device and an air entraining control method. The bleed air system comprises a load air compressor, an anti-surge valve, a controller and a sensor. Wherein the load gas compressor can provide gas for gas utilization equipment of the aircraft, and an angle-adjustable guide blade is arranged at an inlet of the load gas compressor so as to control the exhaust pressure and flow of the load gas compressor. The anti-surge valve is arranged at an outlet of the load compressor and used for releasing redundant gas to prevent surge of the load compressor. The sensor is arranged at an inlet of the gas utilization equipment and used for detecting the pressure and/or flow of gas flowing to the gas utilization equipment in real time. And the controller can automatically adjust the opening degree of the anti-surge valve and the angle of the guide blade based on the detection value of the sensor and the actual demand quantity of t
