| 摘 要： | 研究了挠性航天器姿态跟踪的非线性PID控制技术.基于误差四元数的动力学和运动学方程,运用Lyapunov稳定性理论设计了新型的航天器非线性PID控制器.控制器不仅具有非线性特点,而且比例参数具有时变的特性,能够根据误差的大小自行进行调整,因此比常规PID控制器具有更好的控制效果.另外,控制器可调参数少,计算简单,工程上易于实现,数学仿真证明了控制方法的有效性.

| Abstract: | Nonlinear PID attitude tracking control law of flexible spacecraft is investigated in this paper.The attitude kinematics and dynamics are both described by error quaternions,and a new nonlinear PID control method is designed by using Lyapunov stability theory based on error quaternions equations.The controller has the characteristics of both nonlinear and parameter variety.The proportional parameter can vary with attitude error,so the control law presented in this paper has wider use than that of convention... |
