Abstract:	本論文在於設計及模擬PEARL立方衛星的姿態辨識與控制次系統(ADCS)，PEARL立方衛星是一枚通訊衛星，任務目的為驗證衛星與地面站能以Ka-band通訊，以及科學酬載小型電離層探測儀(CIP)量測影響通訊的電漿密度不規則體，在衛星不同模式中ADCS要能作姿態控制達到指向需求以達成任務。根據衛星需求設計次系統、控制模式與控制流程。使用MATLAB/Simulink以Software in the loop的方式模擬ADCS，建立真實太空中的環境、擾動、軌道、衛星運動學模型用來進行不同運作模式中的控制演算法與模擬。如Detumbling控制、Sun-Pointing控制、LVLH控制、Target-Pointing控制，模擬結果成功達到指向需求穩定衛星。;This thesis is mainly about the design and simulation of Attitude Determination and Control Subsystem (ADCS) for Propagation Experiment using kurz-Above-band Radio in Low earth orbit (PEARL) CubeSat. PEARL CubeSat is a communication satellite with the objective of verifying the communication of the ground station and the CubeSat using Ka-band transceiver, measuring the plasma irregularities of the Earth’s ionosphere that affects the communication systems. ADCS shall be able to control the attitude of PEARL in different operational mode in order to reach the pointing requirements and accomplishing the mission. Designs of the control mode and control process are in terms of the requirements. The ADCS is modeled as a software in the loop with MATLAB/Simulink. A scenario of the real space with environments, disturbances, spacecraft dynamics, sensors, actuators models are created to design the control algorithms and simulations of different control mode. Such as Detumbling control, Sun-Pointing control, LVLH control, Target-Pointing control. The simulation results reach the pointing requirements and stabilize the CubeSat successfully.
