The problem of attitude control of remote sensing satellite using magnetic actuators is considered in this paper. Magnetic actuator was used because it is low power consumption, small mass, low cost and reliable attitude actuator. The attitude control problem of the satellite involves angular velocity suppression, attitude acquisition and finally attitude stabilization will be solved by magnetic actuator only. A comparison between the commonly used controllers for satellite attitude control is presented. The comparison parameters are the total consumed power, the time required to accomplish the angular velocity suppression and attitude acquisition, calculation time of the control algorithm and steady state error in angles and angular velocity. The simulation is done using the complete nonlinear model of satellite. Based on results, a new combined control algorithm was developed to assemble the advantages of these commonly used controllers. Simulation results showed the validity of the developed combined algorithm.
