Description

Technical field [0001] The invention relates to an aircraft real-time simulation platform, in particular to a multi-dimensional four-rotor aircraft attitude control simulation experimental platform. Background technique [0002] In the process of developing quad-rotor aircraft, it is impossible to use real machine test for each aircraft test. First, the cost is too high. Any fully-equipped quad-rotor aircraft is expensive. If it is accidentally damaged during testing, it will Increase the cost of research and development; secondly, it is easy to cause safety accidents. Due to the extremely high instability of the prototype, it is very easy to cause crashes, so the role of the four-rotor aircraft simulation experiment platform is huge. Through the simulation experiment platform, it is possible to verify whether the control algorithm is correct, even if there are errors, it is convenient to quickly adjust the parameters, verify the reliability of the control algorithm in real time,...

AI Technical Summary

Problems solved by technology

[0003] However, the quadrotor unmanned aerial vehicle has strong static instability, and has the characteristics of underactuation, strong coupling and nonlinearity in dynamics, which increase the difficulty of designing the flight controller, so the actual flight experiment is risky and High cost, and more restricted by the surrounding environment

Most universities and scientific research institutions use purely numerical simulation experiments to simulate the flight of aircraft. Although such an experimental method is efficient and convenient, it is difficult to truly show the complex and changeable actual situation, which greatly reduces the confidence of the simulation results.
