Torque maximization and vibration control for AC locomotives

摘要: A traction control system for an ac locomotive optimizes performance by separately controlling the allowable creep level of each individual axle and minimizing torsional vibration per axle. The includes a torque maximizer detector. measures levels determines desired state maximizing detector digitally processes estimated feedback motor in order to detect unacceptable vibration. outputs are provided modulator which these inputs operating As result, is improved while noise due wheel/rail squeal.
