Unmanned aerial vehicle flight control law design method considering rainfall and gust conditions

Abstract

The invention discloses an unmanned aerial vehicle flight control law design method considering rainfall and gust conditions, and the method comprises the following steps: building an unmanned aerial vehicle dynamics model; constructing an environment model, a control surface agent model and an engine agent model, and respectively accessing the unmanned aerial vehicle dynamics model; a flight control law is designed, the flight control law outputs a control surface instruction to the control surface agent model and outputs an accelerator amount to the engine agent model, the unmanned aerial vehicle kinetic model solves the position and attitude of the unmanned aerial vehicle and feeds the position and attitude back to the flight control law, and a closed-loop feedback control loop is formed; and performing tracking control simulation by using a closed-loop feedback control loop, and adjusting a gain parameter of a flight control law. According to the method, the influence of rainfall and gust is comprehensively considered for control law design, the actual motion of the unmanned aerial vehicle under the gust and rainfall conditions can be effectively simulated, reference is provided for stable flight control law design of the unmanned aerial vehicle under the condition of the influence of the rainfall and the gust, and the method has good engineering application value.
