摘　　要：实现针对系统快变量攻角的自适应参数调节是导弹鲁棒增益调度自动驾驶仪设计的一个难点.为解决此问题,提出采用由状态替换方法建立的导弹准线性化模型作为设计模型,基于线性参数时变(LPV)/μ控制技术构造自动驾驶仪设计结构,并通过D-K-D迭代算法设计导弹H∞增益调度自动驾驶仪.所设计的自动驾驶仪不仅能够实现对马赫数和高度两个系统慢变量的自适应参数调节,还能实现对系统快变量攻角的自适应参数调节.非线性仿真结果验证了所提出方法的有效性。It is difficult to design a gain-scheduled autopilot for a missile to realize the adaptive parameter adjustment for the fast varying angle of attack. In this approach, the design model for the missile is the quasi-linear model which is developed by using the state transformation method. The structure of the autopilot is designed based on the linear parameter varying （LPV）/μ control technique; and the H-infinity gain-scheduled autopilot for the missile is designed through the D-K-D iteration. The designed autopilot not only realizes the adaptive parameter adjustment for the slow varying flight Mach number and altitude, but also for the fast varying angle of attack. Nonlinear simulation validates the effectiveness of the proposed approach.
