| Summary: | 碩士 === 逢甲大學 === 航太與系統工程所 === 94 === The estimation and control of systems by using the Kalman filtering theorem is demonstrated; and the selected simulation object, the Formosa-3 satellites developed by the NSPO in Taiwan, is also introduced in this thesis. Under the space environment, the attitude of a satellite will be changed by the external torques. The purpose of this work is to verify whether the controller can overcome the external disturbance and to fulfill the designed objective.
The ideal case which the satellite is “external torques free” is simulated first. After the ideal case is simulated successfully, the case with the external disturbance effects is also included in the Kalman filtering theorem. The noise effects of the measurement and model for the satellite systems are also discussed and surveyed. From the ideal simulation results, the suitable candidate parameters for the case with external torques will be used to verify the theorem used here.
Finally, the simulation results show that the satellite attitude did satisfy the constraints by using the assigned parameters and initial conditions in the Kalman filtering theorem. The results also indicate the system converges within 5000 seconds.
