A Comprehensive Analysis and Solution for Traction Motor Speed Measurement in High Speed Train

Abstract:

In high speed train, to obtain precise speed is important to high performance control, though the transducers used in the train are usually low resolution. The speed measurement was analyzed both on precision and update rate according to the control requirement. A comprehensive measure and calculation solution for traction motor speed measurement is presented. Measure clock period is adjusted according to motor’s different speed range and can obtain good measurement precision both in low and high speed range. The speed update rate can also be guaranteed. The proposed method is implemented and validated by hardware in loop simulation system.
