4/11/2024 0 Comments Uav flight control system![]() The current flight control system uses an IMU, also known as inertial measurement unit, which is composed of three-axis gyroscope, three-axis accelerometer, three-axis geomagnetic sensor and barometer. For flight control, it is necessary to know the current status of the aircraft, such as three-dimensional position, three-dimensional velocity, three-dimensional acceleration, three-axis angle and three-axis angular velocity. The flight control system is mainly used for flight attitude control and navigation. It is undeniable that the development of flight control technology is the biggest driver of UAV changes in this decade.įlight control is the abbreviation of flight control system, which can be regarded as the brain of aircraft. In a few years, UAVs have flown from military applications far away from people’s vision to ordinary people’s homes. ![]() A large number of professional talents in automation, mechanical electronics, information engineering and microelectronics have been invested in UAV research and development. It is usually designed using a three-axis digital gyroscope plus a three-axis digital combination.Nowadays, with the development of chip, artificial intelligence and big data technology, UAV has begun the trend of intelligence, terminal and clustering. The altimeter is mainly used to detect and calculate the high-precision position information of the drone in the air. In order to improve the control stability of the aircraft, gyroscopes and accelerometers are usually used to form a composite gyro structure, which ensures the aircraft's attitude tracking capability and the aircraft's ability to fly smoothly along a given trajectory in various complex attitudes. System integration as required.Ĭurrently, inertial navigation systems, barometric navigation systems and laser gyroscopes are commonly used. In fact, the flight control system of a drone is equivalent to the pilot of a manned aircraft and is the key to the mission of the drone.Īs the core of UAV flight motion control, it must complete the conversion between the two major input parameters and output parameters of the aircraft attitude and position, and at the same time, it must also meet the response speed to control instructions and the stability of the aircraft control under various external interference conditions. This is one of the fundamental reasons why UAVs are different from model aircraft. It is the core system for the UAV to complete the entire flight process such as takeoff, air flight, mission execution, and return to the site for recovery. The flight control system, referred to as the flight control system, is a component that controls the flight attitude and direction of movement of the UAV. So, what parts does the UAV flight control system consist of? Its core is the aircraft control algorithm. A complete UAV flight control system consists of a flight control computer, attitude sensor, radio altimeter, etc. It is the key for the UAV to complete various tasks. In UAVs, the function of the flight control system is to control the attitude and altitude of the UAV, and determine the trajectory and route of the UAV when flying. The core technology of UAVs is concentrated in three aspects: overall technology, power system and flight control technology, which together determine some important technical indicators such as flight altitude, range, flight time, speed, load and so on.
