A Second-Order Sliding Mode Controller Design for Spacecraft Tracking Control

Abstract EN

For spacecraft attitude tracking system, there exists the chattering phenomenon.

In this paper, the spacecraft motion is decomposed into three-channel subsystems, and a second-order sliding mode control is proposed.

This method has been proved to have good convergence and robustness.

Combined with the proposed sliding surface, the three-channel controllers are designed.

The control performance is confirmed by the simulation results, the approaching process is improved effectively, and a smooth transition is achieved without overshoot and buffeting.
