基于自适应PID技术的无尾飞机容错重构控制

Fault-tolerant reconfigurable control of tailless aircraft based on self-adaptive PID technology

无尾飞机是新型飞机的发展方向,与传统的飞机相比,其飞行控制系统更为复杂,故障出现的概率也更大,因此重构控制系统是无尾飞机安全飞行的保障。采用基于自适应PID技术的动态逆控制来研究无尾飞机的重构控制系统,并获得了相应的仿真结果,证实了基于自适应PID技术的动态逆控制对故障具有较好的重构能力,比单独使用动态逆控制更有效。

The tailless aircraft is regarded as one of the developing directions of the new type aircrafts. Compared with traditional aircrafts, the tailless aircraft＇ s control system is more complicated, and the probability of failures is greater. Therefore, reconfigurable control system is important for guaranteeing the safety of the tailless aircrafts. In this paper, dynamic inversion control based on self-adaptive PID technology is adopted for reconfigurable control of tailless aircraft. Simulation results show that dynamic inversion control technology based on self-adaptive PID control has good reconfigurable capability for system＇s failures, and is more effective than using dynamic inversion control technology alone.
