[0023] The present invention will be described in further detail below with reference to the accompanying drawings.
[0024] figure 1 , given the desired input (including the desired three-dimensional position coordinates P d and the desired heading angle ψ d ), which are respectively fed into the backstep sliding mode controller of the attitude loop and the backstep sliding mode controller of the position loop, where the other two desired attitude inputs of the attitude loop (the desired pitch angle and the desired roll angle θ d ) is solved by the backstepping sliding mode controller of the position loop. The controller of the two loops obtains four control variables for the input of the system model. According to the output of the system model, two high-order disturbance observers are designed for the attitude loop and the position loop respectively, which are used to estimate the external unknown disturbance, and calculate the external disturbance. The estimated distu...
