Combining Global and Local Strategies to Optimize Parameters in Magnetic Spacecraft Control via Attitude Feedback
The attitude control of a spacecraft using magnetorquers can be obtained by using attitude feedback, instead of state feedback, with the advantage of not requiring the installation of attitude rate sensors, thus saving cost, volume, and weight. In this work, an attitude feedback with four design parameters is considered. The practical determination of appropriate values for these parameters is a critical open issue. We propose here to search for the parameters’ values which minimize the convergence time to reach the desired attitude.
