When designing a multi-modal flight control system, the core issue is how to divide and define the modality of the system. The main principles are as follows.
According to the type of response required by the mission, the response of the aircraft refers to the time domain or frequency domain response characteristics generated by the aircraft for various control command inputs. Aircraft response classes mainly include: latent response, rate command/attitude hold response, attitude command/attitude hold response, track command/track hold response, vertical rate command and altitude hold command response, etc., as well as lateral heading response. Different response types are determined to suit the needs of different missions, so the response type can be used to control the division of multi-modality. A significant feature of the fly-by-wire control system compared to the mechanical system is that the flight control law can be tailored to the mission, thus ensuring that the aircraft achieves the best flight quality when performing different missions at different flight phases.
According to the flight phase, the entire flight from takeoff to end of mission (return to recovery or crash) can be divided into multiple flight phases. In different flight phases, due to aircraft characteristics, completed missions, and the surrounding environment The conditions and the requirements for flight quality are different, and the control laws of the flight control system are also different, so that the multi-modal control law can be formed.
According to the function division of the flight control system In order to enhance the maneuverability of the aircraft and increase the mode of the aircraft, in addition to the use of special aerodynamic layout design, the use of a specially constructed control system is also the most effective method. In order to achieve a special maneuvering method, different control system structures should be constructed to form a specific control mode. For example, in order to achieve large-angle hovering maneuvers, large submersible maneuvers, and sharp climb reversing maneuvers (composite maneuvers), full-capacity gyro or "striped" platforms are required to provide different full-featured cover feedback variables, requiring additional aircraft fuel positive overload ( Prevents the lack of oil supply when the aircraft is tumbling, as well as control software, and generates control commands to manipulate different rudder surfaces and throttle mechanisms in accordance with specific control laws, from forming specific control system structures and control modalities.
According to the control system redundancy management requirements, the UAV flight control system is divided to improve the reliability and safety of the control. The reliability configuration and the safety software are often used on the basis of sensors, actuators and control software with certain reliability, such as no one. The aircraft flight height measurement link can use similar residuals, that is, multiple identical sensors (such as four radio altimeters), or non-similar similarities, that is, completely different sensors (such as GPS, radio altimeter, atmospheric computer, etc.) ). It can also be formulated in a similar mixture with similar abundance. With redundancy configuration technology, it needs to be effectively managed. And determine or switch the task mode according to the fault, such as the normal working mode, the degraded working mode, the backup working mode, the reconstructed working mode, and the like.
carbide Twist drill are the most common type of drill bit and are used for everyday drilling in all types of material. They are also the most confusing due to the sheer number of size, tip, and material specifications.
hese are the most common twist drills and are a good compromise between length and strength
