摘要:
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(QuantitativeFeedbackTheory,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。

Abstract:
The introduction of the full paper discusses relevant matters and then proposes the design mentioned inthe title,which we believe is new and better than previous ones and which is explained in sections 1, 2 and 3.Sec-tion 1 briefs the conventional mathematical model of the pitch channel of the attack UAV.Section 2 presents theQFT robust control principles.Section 3 discusses improved robust flight control system design based on QFT; itscore is that the flight control system of the pitch channel we designed takes into account the parameters of boundaryuncertainties and large time-varying range.The simulation results,given in Figs.8,9 and 10,and their analysisshow preliminarily that the flight control system thus designed has strong robustness against the parameter uncertain-ties of the UAV with full flight envelope.
