本文以某个虚构的巡航式飞行器的飞行控制系统为研究对象，首先讨论了一个简单的总体方案，然后根据此方案，在详细分析此飞行器运动学与动力学的基础上，建立了飞行器飞行仿真数学模型，并在允许的条件下进行简化得出了此飞行器线性化小扰动短周期运动模型与传递函数仿真模型。 - Then in allusion to biased momentum wheel system , based on classical control system a pid controller was design about pitching channel . according to specialty of roll - yawing channel , this paper discuss long - time cycle movement and short - time cycle movement . when design the control method of long - time cycle movement , whiff thruster is used to assistant the control system . when design the control method of short - time cycle movemen , in order to sovle the problem of coundn ’ t abtain the angular velocity signal , nonminimum phase controller advanced by terasaki is used
然后针对偏置动量飞轮系统,基于经典控制理论设计俯仰通道的pid控制律,根据滚动?偏航通道耦合的特点,分别讨论了由轨道角频率和章动频率引起的长周期运动和短周期运动。其中长周期运动控制律设计时,结合了喷气推力控制来辅助偏置动量控制;短周期运动控制中,为了解决不能获得角速度信号的问题,采用terasaki提出的非最小相位控制器进行控制。
