| 摘 要： | 在极地圆轨道上工作的对地定向磁控小卫星，其动力学方程是一个线性周期系统。根据极地轨道地磁场变化的特性，利用卫星的姿态角和姿态角速度作为反馈信号，提出也一种采用磁力矩器的比例微分控制规律设计方法。

| Abstract: | The magnetic control system for polar orbiting,nadir pointing small satellite is studied in this paper.It is shown that the dynamics with magnetic control system is a linear periodic system.Taking into account properties of the geomagnetic field,a new PD magnetic control law using the feedback information of attitude angle and attitude rate is developed.The PD controller has periodically time varying gains to ensure the control system for required transient and steady performance. |
