Belt driving systems applied to many kinds of equipment for industrial machinery encountered a vibration resonance problem due to the increase of the operational speed. In order to reduce this resonance vibration, we proposed parametric excitation feed-forward control using torque fluctuation. A drawback is not being able to apply it for multi-exciting sources. Alternative ideas are proposed in this paper, which are bang-bang feedback control using sign function based on variable structure system theory. These methods are nonlinear control to fluctuate belt tension using bang-bang switching defined on displacement-velocity phase plane of detected belt vibration. The stable conditions in terms of control phase were detected. The control effects were confirmed theoretically. As a result, these bang-bang feedback control methods are effective and have many practical advantages for usage.
