| 摘 要： | 电磁卫星编队位置跟踪是存在输入延时和扰动不确定的控制问题,以卫星相对运动CW方程作为动力学模型,采用前馈加反馈的方式控制编队运动跟踪预定轨迹,前馈控制量由预定轨迹结合CW方程给出,反馈控制采用状态线性变换后的滑模变结构控制律.证明了滑模切换面可达以及滑模面上的运动与不确定扰动无关.数值仿真表明考虑时滞的控制相比未考虑时滞的控制,位置跟踪精度有所提高.

| Abstract: | Electromagnetic satellite formation station-tracking is a control problem with input delay and disturbance uncertainties.Taking CW equation as dynamics model,a control law including feed-forward plus feedback is used for the station tracking.The feed-forward control quantity is calculated based on the predetermined trajectory and the CW equation.The feedback control adopts sliding mode variable structure control law with state linear transformation.It is proved that sliding manifolds are reachable and slidi... |
