Adaptive Sliding Mode Control For A Constant Tension Suspension System

The constant tension suspension system (CTSS) can be used to counteract the gravity of experimental spacecraft, and is widely used in the ground test of spacecraft control schemes. In this paper, the mechanical model of a CTSS is established, and an adaptive sliding mode controller (ASMC) is designed for the CTSS. The simulation results show that the transient time and steady-state error of the ASMC system are small, which satisfies the requirements of microgravity simulation.
