Focused on the problem that the take-off of a small unmanned helicopter(SUH)mainly depends on the control of the hand-operated,an automatic take-off method for SUH is proposed and the circuit is implement.First,through acquisition of hand-operated small helicopter take-off large amounts of data,establish the height of the helicopter,and get the relationship between altitude,throttle and collective pitch.Second,a modified adaptive model of control algorithm to control altitude was presented,and a weighted differential feedback control of posture and sliding motion are used.they are arming to keep the ground force so that the SUH can take off vertically,get the desired of altitude.However,and the control flowchart of automatic take-off was designed by FPGA(Field Programmable Gate Array).Through the flight state was precisely controlled the steering gears on the helicopter.At last,the result of experiment conducted on the ATRE 600 is used to test platform so that the control strategy was efficient.
