摘要
Abstract
To reduce the cost and improve the reliability of micro-satellites,a method which employing magnetic torques as the only actuators was developed to realize three axis stable control.Then by using linear quadratic regulator(LQR)optimal control theory,the infinite time state regulator and steady gain regulator were designed to stabilize micro-satellite to nadir pointing using fully magnetic torques.Meanwhile,taking KaiTuo-1 satellite in-orbit flight as the research object,the product of inertia,orbit inclination,residual magnetism and aerodynamic drag disturbance that brings different effects for the control precision were analyzed.Simulation results validate efficiency and practicability of LQR controller.It can achieve high control precision under little disturbance.关键词
