针对攻击型无人机这一类参数大范围时变并且带有参数有界不确定性的对象,提出了一种基于定量反馈理论(Quantitative Feedback Theory,QFT)与预定增益控制理论相结合的飞行控制系统设计新方法,并基于该方法设计了攻击型无人机俯仰通道鲁棒飞行控制系统。仿真结果表明,所设计的飞行控制系统对于无人机全飞行包线内参数变化及参数有界摄动具有强鲁棒性。
Aiming at the large-scale time-varying and uncertain bounded objects with the parameters of attack UAVs, this paper proposes a combination of quantitative feedback theory (QFT) and pre-determined gain control theory Control system design new method, and based on this method, design a robust flight control system of attack UAV pitch channel. The simulation results show that the designed flight control system is robust to the variation of the parameters and the bounded perturbation of parameters in the UAV flight envelope.
