摘要
研究了BTT导弹滚动通道自动驾驶仪的设计问题.BTT导弹滚动通道自动驾驶仪的数学模型是一个时变的二阶线性模型,其设计目标是使滚动角γ跟踪给定的指令.利用提出的稳定鲁棒性理论和时变系统的镇定理论,并结合滚动通道自动驾驶仪模型的特点,设计了一个完全确定的,即在全程弹道上无需切换的自动驾驶仪,并证明了其在全程弹道上的稳定性、一致渐近跟踪性、鲁棒稳定性和鲁棒一致渐进跟踪性;最后对所设计的自动驾驶仪在弹道的7个特征点上作了定点仿真,得到了令人满意的结果.
The problem of designing an autopilot of a roll channel of a BTT＂ missile is considered. The mathematical model of the autopilot of the BTT＂ missile is a time-varying second-order linear system. The design objective is to let the rolling angle γ track a desired signal. Based on the theory of robust stability, stabilization of the time-var-ying systems and the characteristics of the roll channel of the BTT missile, an entirely fixed autopilot with no necessity of switch for the entire trajectory is designed, and the stability, uniform asymptotic tracking property, robust stability and robust uniform asymptotic tracking property are proven. Simulation results at seven characteristic points of the designed trajectory show the effect of the proposed method.
