摘　　要：对舰载飞机着舰时的复飞决策、复飞操纵问题进行了研究。在建立舰载飞机着舰复飞的非线性飞行动力学模型的基础上,讨论了复飞包线的生成方法,重点研究了复飞操纵动作对复飞包线的影响,对不同的操纵方法进行了计算和比较,建立了复飞时最优的操纵规律及相应的复飞包线,开发了复飞决策及操纵模拟系统,对上述方法进行了模拟验证。仿真计算表明,优化操纵升降舵可以极大地缩小复飞危险区域,采用模糊控制器则可实现自动复飞。Wave-off decision and control of carrier aircraft are studied. Based on six-freedom nonlinear equations of flight dynamics, the method of generating a wave-off envelope is discussed, and the study is focused on an impact of the wave-off controls on the wave-off envelope. Comparing three different controls （ power control only, optimal elevator control and fuzzy logic control on elevator） , the optimal control of wave-off and its corresponding wave-off envelope are established, and a simulation system of wave-off decision and control is developed to verify those methods. The results of simulation show that the risk region of wave-off can be greatly reduced by optimizing the elevator control, and a fuzzy controller can lead to automatic wave-off.
