Performance Analysis of Re-adhesion Optimization Control Based On Full-dimension State Observer

Slip/slide phenomena between wheels and tracks often happen in metro traction, which result into bad traction/ braking performances. A re-adhesion optimization control method based on full-dimension state observer is briefly present in the paper. The control performances, including system stability and convergence speed, are analyzed from two aspects. One is the closed-loop poles configuration, while the other is system parameter deviations. Simulation and experiment results indicate the proposed control has the desired torque response and fine re-adeshion effects.
