Design of Longitudinal Anti-Disturbance Control System for Aircraft Based on Distributed Parallel Algorithm

摘要

Aiming at the problem of poor control stability of traditional aircraft control systems, the longitudinal anti-disturbance control system based on the distributed parallel algorithm was designed. Based on the hardware of the original control system, the anti-disturbance control system was designed. And the software part of the aircraft longitudinal anti-disturbance control system was designed. The longitudinal model of aircraft was established, and the active disturbance rejection controller (ADRC) was also designed according to the model. Through the use of distributed parallel algorithms to set the parameters of ADRC, thus completing the design of the vertical ADRC system The comparison experiment with the traditional PD-based aircraft control system shows that the design of the control system based on distributed parallel algorithm has the characteristics of less overshoot, good stability and broad application prospects.
