Singularity-free integral-augmented sliding mode control for combined energy and attitude control system

摘要: A combined energy and attitude control system (CEACS) is a synergized in which flywheels are used as actuators simultaneously power storage system. This paper, subsequent to previous research on CEACS, addresses the attitude-tracking problem. Integral Augmented Sliding Mode Control with Boundary-Layer (IASMC-BL), locally asymptotically stable controller, developed provide robust accurate solution for CEACS’s The controller alleviates chattering phenomenon associated sliding mode using boundary-layer technique. Simultaneously, it reduces steady-state error an integral action. paper highlights uncertainty of inertia matrix contributing factor singularity inversion uncertain simulation spacecraft dynamics also identified leading singular situation. Therefore, avoidance strategy proposed this guarantee singular-free behavior faces uncertainties. maiden work attempts employ singularity-free (IASMC-BL) robust, nonsingular CEACS.
