摘　　要：解决了机动再入飞行器在气动系数变化范围大和气动耦合严重等恶劣条件下的姿态和过载控制问题 .为了能充分利用飞行器可测量信息提高系统自适应能力 ,提出了滚动通道状态方程参数辨识—级点配置—前馈补偿自适应控制和横向通道基于攻角反馈以过载为主控信号的变参数自适应控制的自动驾驶仪设计方法 .通过对某飞行器的制导控制系统仿真 ,可以看出该自动驾驶仪使飞行器有很好的飞行性能 .The control of attitude and acceleration for maneuvering entry vehicles is obtained in the case that the aerodynamic parameters changing in the large-range and the pneumatic coupling is very strong, in which the control of attitude and acceleration is rather difficult. In order to improve the adaptation property of the system by using the available information, a new design method for vehicle autopilot is presented on the basis of both the pole-assignment adaptive control with parameter identification of the state equation and feed-forward in the roll-channel and the changing parameter control with attack angle feedback in the lateral-channel. The simulation shows that the proposed design method provides a good flight performance for maneuvering entry vehicles.
