Active magnetic control of gravity gradient satellite using 3 magnetic torquers / Mohd Naim B Mohd Sabri

Active magnetic control of gravity gradient satellite using 3 magnetic torquers
ABSTRAK Tesis ini adalah berkaitan dengan pemodelan pengawal kepada satelit kecerunan graviti. Salah satu teknik pengawalan yang telah digunakan untuk satelit jenis ini adalah teknik pengawalan magnetik. Jadi, di dalam projek ini akan menganalisis kawalan sikap magnetik terhadap satelit kecerunan graviti. Tiga magnetik akan digunakan dan diletakkan disepanjang paksi utama satelit. Seterusnya, perbandingan sudut Euler diantara sikap satelit terdahulu dengan yang telah ditambah magnetik tork selepas pemodelan simulasi. Di sini, kesemua keputusan kajian didapati daripada pemodelan simulasi yang direka bentuk dengan menggunakan program MATLAB SIMULINK. Selain itu, kajian ini mengambil pakai data-data dan keadaan asal dari satelit mikro pertama Malaysia, TiungSAT-1 sebagai rujukan. Di akhir kajian, pemahaman tentang kegunaan magnetik tork terhadap satelit kecerunan graviti dengan misi satelit. Keputusan kajian membuktikan bahawa sudut Euler dapat dikawal dengan lebih baik dengan kewujudan pengawal. ABSTRACT This thesis deals with design of controller for gravity gradient satellites. One of the control techniques that have been used on this type of satellite is magnetic control technique. Thus, in this project the magnetic attitude control of the gravity gradient satellite will be analyzed. Three magnetic torquers will be used and placed along the satellite primary axes. Then, the comparison of the Euler Angle between original properties of satellite and after added with the torquers can be made after the simulation is done. In this, the results of the research are obtaining from the simulation models that designed from MATLAB SIMULINK software. On the other hand, the development is taking the first Malaysia microsatellite, TiungSAT-1 as the references model of it characteristic and initial conditions. At the end of this project, should understand the role of the three magnetic torquers to the gravity gradient satellite due to the satellite missions. The findings of this project also prove that Euler angles of the satellite can be control with more accurate with the existence of the controller.
