Abstract
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. 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. 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.
Highlights
Statistical data reported in [1] reveal that 27 % of all operations on Ukrainian railroads are performed by shunting locomotives
An analysis of the process to renovate the means of traction on world railroads shows [2, 3] that the polygon of railroads where the traction of diesel locomotives is applied, as well as the amount of transportation performed by diesel locomotives on railroads, occupy a leading place
Based on the analysis conducted, we can conclude that the nonlinear object of control, the valve-inductor engine (VIE) in combination with a hybrid set, requires the application of custom systems based on fuzzy control algorithms
Summary
Statistical data reported in [1] reveal that 27 % of all operations on Ukrainian railroads are performed by shunting locomotives. Shunting locomotives are widely employed at industrial enterprises Such operations imply the transportation of a small amount of cargo on short distances (for example, within a station, or an enterprise), which is why using powerful locomotives is impractical. Industry control systems almost) completed the process of introduction of advanced types of traction (which led to a certain decrease in the output of diesel locomotives in some countries), the need for diesel locomotives will remain stable in the world. The result of the global trend for improving energy efficiency is the need to transfer to more environmentally-friendly and reliable types of shunting traction rolling stock. They represent of the most important controlling elements of railroad stations that ensure smooth operation. Given the above, creating hybrid assemblies for shunting traction with prospective control systems is one of the important scientific-technical tasks in railroad transportation
