Aircraft 4D track simulation system and simulation method based on fuzzy pid control

Abstract

The invention discloses an airplane 4D flight path simulation system and method based on fuzzy PID control. The system comprises a database server and a microcomputer for man-machine interaction, wherein the database is connected with the microcomputer through a digital network. The system is advantageous in that the system give integrated consideration to the factors which affects the flight, such as the performance of an airplane, a flight program and an atmospheric environmental; the flight path simulation path is built, and facilitates the improvement of the precision of flight path simulation. When the precision of flight path simulation meets certain requirements, the system guarantees that the airplane cannot generate side and vertical collision risks from airspace design according to a 3D flight path obtained through simulation and an operation path of a protection region in the air. The system provides a bigger autonomous right for a unit through the advanced airborne equipment and navigation system, enables the burden on the aircraft operation organization and flight control and command to be reduced, enables the level of flight delay to be controlled within a range which can be accepted by tourists, reduces the occurrence rate of the flight delay, and can provide more excellent air transportation services for airport passengers.

Description

technical field [0001] The invention belongs to the technical field of modeling of a 4D track simulation system, in particular to an aircraft 4D track simulation system and a simulation method based on fuzzy PID control. Background technique [0002] In recent years, with the continuous development of the global economy, the number of civil aviation aircraft has continued to increase, and the flight traffic has also continued to increase. The rapid growth of air transport volume objectively requires the construction and management of civil aviation to adapt to it. As the foundation of the U.S. economy, civil aviation has been a catalyst for U.S. economic growth and has had a profound impact on everyday life, and is expected to grow by 150% to 250% over the next two decades, even with conservative estimates, now Some and planned capacity simply cannot meet the growing demand. For this reason, in order to ensure that the next-generation U.S. air transportation system can meet...
