| 摘 要： | 以某型固定翼飞机为例,针对协调转弯时侧滑过大的现象,采用了鲁棒H∞状态反馈控制与常规PID(Proportion Integration Differentiation)相结合的控制方法设计控制律结构.基于固定翼飞机线性化模型,研究了H∞状态反馈在横侧向控制律设计中的应用,并分析了滚转角和飞机速度对转弯半径的影响.仿真结果表明所设计的控制律可行有效,同时验证了对影响转弯半径因素理论分析的正确性.

| Abstract: | Taking certain fixed-wing airplane as example, the controller structure of H∞ state feedback control combined with proportion integration differentiation (PID) was designed to solve the sideslips of coordinated turns. Based on the fixed-wing airplane linearization model, the application of H∞ state feedback in the lateral controller design was studied and the influence of roll angle and airplane speed on the turning radius was analyzed. The results indicate that the designs are feasible and effective, and theoretical analysis about the factors affecting the turning radius is correct . |
