Quality assessment of control over the traction valve-inductor drive of a hybrid diesel locomotive
Journal Title: Восточно-Европейский журнал передовых технологий - Year 2018, Vol 1, Issue 2
Abstract
<p>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.</p><p>Control systems based on a modal controller and fuzzy logic were synthesized. It is established that the modal controller has the following quality indicators: maximal overshoot – 12.27 %, re-adjustment time – 5.08 s, number of oscillations – 2. For the FPID-controller, the quality indicators are: 3.75 %, 3.01 s, and 1, respectively. Thus, on analyzing the quality of their operation, it was found that the best indicators were demonstrated by the FPID- controller.</p><p>The built physical model of the valve-inductor drive, specifically the system wheelset-engine with a control system that employs the fuzzy algorithm of speed regulation, confirms the feasibility of a fuzzy controller.</p>
