摘　　要：从伪攻角三回路自动驾驶仪的数学模型出发,分析了系统稳定边界,给出了最大允许的机体不稳定度经验公式。结合工程应用情况,建立了控制参数与闭环极点的简便解析关系,并对控制参数进行了预测校正。实例分析表明该方法便捷有效,收敛速度快,适用于静稳定性快速变化的飞行器三回路自动驾驶仪的设计。Starting from the mathematical model of a pseudo AOA three-loop autopilot,this paper analyzes the system stability boundary and provides an empirical formula for the maximum allowable instability of the airframe.Based on engineering applications,a simple analytical relationship between control parameters and closed-loop poles is established,and the predictive correction of control parameters is performed.The case analysis shows that this method is convenient and effective,with fast convergence speed,and is suitable for the design of three-loop autopilot for aircraft with rapidly changing static stability.
