Multi-Train Movement Simulation Using MATLAB Object-Oriented Programming

Abstract

This paper is to demonstrate the use of MATLAB Object-Oriented Programming (OOP) for developing Multi-Train Movement Simulation (MTMS). Dynamic performance of the train movement is modeled with the help of Newton’s law of motion. Train movement in this work is based on a sequence of four operating modes: i) accelerating mode, ii) constant speed or cruising mode, iii) coasting mode and iv) braking mode. The design concept of a train movement class is described with its properties and methods. To evaluate its use, the proposed train movement simulator developed here is tested against Bangkok Transit System (BTS) – Sky Train Silom Line. This system has the service distance of 13-km and is fed by seven 750-V DC power sources through its 3rd rail. The results showed the effectiveness of the proposed simulator.
