Detecting and minimizing centrifugal and sliding processes of short-range electric railway vehicle involves locking control loop if maximum revolution rate difference exceeded and nulling

摘要

The method involves locking a control loop for a time determined by a control signal if a maximum value for the difference between the engine revolution rate and a reference revolution rate characterizing the vehicle speed is exceeded, setting to a null initial value followed by releasing the control loop. The revolution rate difference is then controled back to the initial desired value.
