Embodiment Construction
[0068] The following will clearly and completely describe and discuss the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all examples. All other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
[0069] Such as figure 1 As shown, the present invention discloses a hybrid control method of attitude and position of a DIC-PID-based quadrotor aircraft, comprising the following steps:
[0070] Step 1: Treat the quadrotor aircraft as a single rigid body, obtain its nonlinear dynamic model through the Newton-Euler equation, and establish the input-output relationship of the system;
[0071] Step 2: Based on the DIC dynamic inverse control theory, perform attitude control on the inner loop of the quadrotor aircr...
