摘　　要：三轴稳定控制是大挠性飞行器有效和重要的姿态控制方式，喷嘴控制是实现三轴稳定控制的手段之一。本文针对伪速率调制器（ＰＳＲＭ）和脉冲调宽调频调制器（ＰＷＰＦＭ），采用非线性脉冲调制器线性化和描述函数两种方法来分析大挠性航天飞行器的姿态稳定性问题，并对某型卫星的远地点点火姿态控制系统进行了分析和仿真。Three axes stability control is an efficient and important method for large flexible spacecraft attitude control Jet control is one method to realize this In this paper,as to two nonlinear jet modulators named pseudorate modulator (PSR) and pulse width pulse frequency modulator (PWPF),two methods that are linearization and describing function of nonlinear pulse modulator are adopted to study attitude stability for large flexible spacecraft The system of apogee fire attitude control of some satellite is studied
