| Popis: | Slip controller is an essential part of the locomotive controller because it enables maximum force transfer and increases the service life of the locomotive parts. The modern slip controllers try to determine actual adhesion parameters and set the required tractive force to avoid slippage occurrence. Many types of the slip controller methods were developed, and one of developed principle try to determine adhesion parameters from phase shift between motor torque and corresponding speed measured on the motor or wheelset. The paper presents a novel evaluation procedure for the phase shift calculation that is based on the Kalman filter that enables directly compare force corresponding with the motor torque and the adhesion force. The method principle is described in the paper, and the method performance is evaluated on the mathematical model. |
