Sliding Mode Control for ttitude Tracking of Thruster-Controlled Spcecraft

Yee Jin Cheon

Abstract

Nonlinear pulse width modulation (PWM) controlled system is considered to achieve control performance of thrustercontrolled spacecraft. The actual PWM controlled motions occur, very closely, around the average model trajectory. Furthermore nonlinear PWM controller design can be directly applied to thruster controlled spacecraft to determine thruster on-time. Sliding mode control for attitude tracking of three-axis thruster-controlled spacecraft is presented. Simulation results are shown which use modified Rodrigues parameters and sliding mode control law to achieve attitude tracking of a three-axis spacecraft with thrusters.

Keywords sliding mode, pulse width modulation, modified Rodrigues parameters, nonlinear system, average model
