Method for creating band elimination filters in electric filters for rail vehicles

摘要

The method involves supplying an output signal i.e. main current (Inetz) of a control device to an output of a filter (1), and controlling a voltage source with an output signal (Uq) of the control device. The control device is designed according to a principle of repetitive control, and is formed from a resonances subsystem with transfer function and a stabilization subsystem. The stabilization subsystem is designed according to a method under inclusion of filter parameter such that a regulated distance and the control device are stable and causal.
