衛星姿態控制:Hinf 方法

Abstract

摘要 本論文主要在利用 方法來作衛星姿態控制器設計，建立簡單的衛星模型，進行MATLAB，及SIMULINK的模擬並與比例微分(Proportional-Derivative,PD)控制器來作比較分析。經由模擬結果得知 控制器在有干擾力矩的情況下，角度誤差、角速度誤差皆為PD控制器的二分之一到十分之一左右。顯示 控制器有良好的性能表現及強健性。

ABSTRACT The main purpose of this thesis is using method to design the satellite attitude controller,and establish a simple satellite model.We use MATLAB and SIMULINK to do simulation of this controller and analyze,then compare with PD controller. Simulation results show that under the condition of disturbance, the auttitude error and angular rate error of controller are 50% to 10% that of PD controller.This show that the controller has good performance and robustness.
