Abstract Accuracy of position and orientation of satellite or commonly it’s called satellite attitude, which is important to support the main point of satellite. When satellite skyborned on particular orbit trajectory on fixed axis, noises are happened to interrupt the path. LQR methods is used to solve the big noises are happened on stability of satellite orbit by without happened decreasing of satellite coefficient performancy. Beside that, LQR can solve the noise which has happened before in a shorter time and minimize the kinds of noise. On this final project, we analyze the stability of state space of attitude control on rotor spacecraft by using linearization on system. Then, we analyze LQR methods and divide by uncontrolled system, so we get an stabil of asymptotik from system and stability is gotten in shorter time by minimize the noise.
