The present invention relates to an FPGA-based drone flight control system equipped with a lidar and, more specifically, to an FPGA-based drone flight control system equipped with a lidar, capable of increasing efficiency in terms of weight and power consumption by enabling control by a single chip due to FPGA-based operation, and having hovering and collision avoidance functions. The FPGA-based drone flight control system equipped with the lidar, enabling purpose-customized program design based on FPGA and employing a lidar sensor, includes: a sensor part provided on a drone to sense the speed, acceleration, angular speed, azimuth, and obstacle position of the drone; a flight control part provided on the drone to perform navigation calculation, posture control calculation, rotor control, and servo motor control; and a ground control part applying a command signal to the flight control part such that the drone performs automatic flight, movement to a target spot or hovering. The flight control part also includes an algorithm input module receiving an algorithm so as to control navigation calculation, posture control calculation, rotor control, servo motor control, automatic flight, and hovering in a preset manner.
