The controller introduces additional compensation for disturbances, velocity and acceleration of tracking signals, and a new sliding approach law for the SMVSC was defined, then the system meets the conditions for the existence of generalized sliding mode. The experiments on one singleaxis flight simulator show that the proposed control scheme improves the tracking performance with more robustness against parameter uncertainty and extern disturbance, contrasted with the traditional PD+DOB scheme.
