Abstract：The Noether symmetry and conserved quantity for singular variable mass controllable nonholonomic systems on time scales are studied. First based on the Hamilton principle on time scales， the motion equation of the singular variable mass controllable nonholonomic systems on time scales is established. Then according to the invariance of the Hamilton action under infinitesimal transformations， the criterion of Noether's generalized quasi-symmetry and the Noether generalized quasi-symmetry corresponding conserved quantity of the systems are given. Finally the application of the research results are illustrated by examples.
