Quality assessment of control over the traction valve-inductor drive of a hybrid diesel locomotive

Abstract

EN: We have studied the valve-inductor drive for its application as a traction motor in a hybrid locomotive. We identifying parameters of the valve-inductor engine and built its simulation model based on a Lagrange equation. The model constructed makes it possible to take into consideration non-linearity of the engine. We have synthesized a modal speed controller and a controller based on fuzzy logic for the valve-inductor drive of a hybrid locomotive. The operation of two types of controllers was analyzed in terms of their influence on the basic quality indicators of control; it was found that the fuzzy controller was better at processing the set value of input magnitude. We have designed a simulation model of the traction valve-inductor drive of a hybrid locomotive with a fuzzy speed controller, and studied its work along a railroad section with actual profile and limitations.

UA: Ідентифіковано параметри вентильно-індукторного двигуна та створена його імітаційна модель. Синтезовано модальний регулятор швидкості та регулятор на базі нечіткої логіки. Проаналізовано роботу двох типів регуляторів на основні показники якості регулювання. За результатами аналізу встановлено, що нечіткий регулятор більш точно відпрацьовує регульовану величину.
