摘　　要：研究飞行器机动飞行优化控制,针对碟形飞行器复合控制系统是一个高度非线性的多输入系统,为了提高飞行器动态特性,通过对碟形飞行器所受合外力和力矩的分析并根据纵向运动假设得到碟形飞行器纵向运动简化方程,进行小偏差线性化得到纵向通道变质量矩/推力矢量复合控制线性化方程。由于线性系统是静不稳定的并且是非最小相位系统,传统的控制方法无法直接使用,针对碟形飞行器变质量矩/推力矢量复合控制系统,设计了可以处理这类问题的广义预测控制器并进行了仿真,结果与PD控制的仿真结果进行了对比,结果表明广义预测控制可以提升系统的响应速度,为设计提供了参考依据。Saucer-like air vehicle longitudinal locomotion simple equation is obtained by analysis of the external force and moment of saucer-like air vehicle and by longitudinal locomotion hypothesis.Then longitudinal locomotion linear equation of the compound control system of the saucer-like air vehicle is obtained by small deviation linearization.A GPC controller has been designed for variety quality square and thrust vector compound control system of saucer-like air vehicle and carried on emulationl research,and was compared with classical PD controller.Simulation results show that the VSC controller has a better control performance.
