Sliding Mode Control for Detumbling Rigid Spacecraft with Underactuated Configuration

摘要

This paper discusses the problem of detumbling a rigid spacecraft with underactuated configuration of one-sided thruster. First, some new definitions on the configuration of one-sided thruster are introduced, such as completeness andincompleteness, and the incomplete configuration is divided into two cases: disturbance-free two-dimensional complete configuration for three-dimensional control and two dimensional complete configuration with disturbance for three-dimensional control.For the latter one a special case as disturbance-coplaner two-dimensional complete configuration is considered to stabilize the angular velocities of a rigid spacecraft, in which a Sliding Mode Control (SMC) law is used. The simulations show theeffectiveness of the approach.
