| 英文摘要 |
| We start by giving the detailed design process for a quad-rotor mini unmanned aerial vehicle, including the
airframe design, propulsion system, autopilot, sensors and wireless communication. By using Newton-Euler’s laws, we
analyze the dynamics of such an aerial vehicle to derive for it a 6-degrees mathematical model with parameter values
measured and calculated. To meet the requirement on fast tracking performance, we develop a closed-loop control system
based on the concept of fast terminal sliding-mode control, and prove its stability by using Lyapunov function. This control
system is composed of two nested control loops: the inner loop for the attitude control and the outer loop for the position
control. Simulation results show that the proposed method can provide robustness and good tracking performance for the
designed quad-rotor mini unmanned aerial vehicle. |
