Abstract

The invention discloses an auto disturbance rejection control method and device for an aircraft. The method includes the following steps that: the operating parameters of the power portion of the aircraft are collected; the attitude dynamic model of the aircraft is generated according to the operating parameters; the attitude dynamic model is converted according to a preset control model, so thata state model can be obtained; an auto disturbance rejection controller is established according to the state model; and the flight attitude of the aircraft is controlled according to the auto disturbance rejection controller. With the auto disturbance rejection control method and device for the aircraft of the invention adopted, the technical problem of complicated parameter setting due to the need to adjust a plurality of parameters in a control technology for compensating uncertain factors in the prior art can be solved.

Description

technical field [0001] The invention relates to the application field of automation technology, in particular to an aircraft active disturbance rejection control method and device. Background technique [0002] With the development of aerial photography technology, various types of aircraft mounted with shooting devices are also derived. However, how to make the aircraft freely adjust its flight attitude in the air has become a problem that the industry is eager to solve. [0003] Taking aircraft such as UAVs as an example, so far, the control algorithm of UAVs basically adopts the traditional Proportion Integration Differentiation (PID) controller. The advantage of this algorithm is its simple structure. However, it is difficult to achieve high-precision and robust control when the aerodynamic parameters of UAVs vary greatly, high-order nonlinearity, strong coupling, and structural parameters are unstable. [0004] Although ADRC (Auto Disturbance Rejection Controller, refe...
