Aircraft trajectory control method fused with Gaussian process

Abstract

The invention discloses an aircraft trajectory control method fused with a Gaussian process. The aircraft trajectory control method comprises the following three parts: three-dimensional data collection, Gaussian process modeling and model prediction control. According to the method, model predictive control is used as a master control algorithm, meanwhile, a Gaussian process is fused to predict the process of the next moment, the model predictive control fused with the Gaussian process is combined with the motion speed track of the four-rotor aircraft, and the method has certain high efficiency, accuracy and real-time performance. And the trajectory tracking error of the aircraft can be effectively reduced. According to the aircraft trajectory model predictive control method, the optimization difficulty in the model predictive control process is reduced by sampling the data set in the training sample, and the stability of model predictive control is improved.

Background technique [0002] Aircraft will be affected by air resistance when flying in the atmosphere. These complex aerodynamic effects become a significant disturbance at high speeds, causing large tracking errors to be introduced during flight and extremely difficult to model. To achieve high-speed flight, feedback control must be able to account for these aerodynamic effects in real time. This requires an accurate and efficient control method for evaluation.
