Take research on control strategy for the case that the remote control failure when the unmanned helicopter landing. First, analyzed the impact of the ground effect on the landing of the plane, and it is concluded that the aircraft should accurately measure the height of the plane and preset the reasonable descent speed when it is near the ground. The accuracy and real-time of the height measurement are ensured by combining the vertical velocity and the ultrasonic measurement information. Then, put forward the control strategy of safety landing of the unmanned helicopter when it's remote control failure. Finally, design the hardware-in-the-loop simulation platform to verify the feasibility of the design. The simulation results show that the autonomous landing control strategy designed in this paper can successfully complete the safe landing task.
