A Digital Real-Time Simulator for Rail-Vehicle Control System Testing
نویسندگان
چکیده
Modern electrical locomotives are powered by controlled power converters. Integration testing of the vehicle control system is performed using real-time simulation. The present contribution presents an evaluation of a digital real-time simulator for this purpose, with particular emphasis on switching and events, which is one of the more demanding tasks in the real-time simulation of hybrid systems. A pragmatic solution to the difficult problem of simulating hybrid systems in real-time is proposed.

Rail vehicle control system integration testing using digital hardware-in-the-loop simulation
Abstract: Control systems for converter-controlled rail vehicles are orders of magnitude more complex than controllers for previous generations of vehicles. While the dynamic behaviour of previous generations of vehicles was to a large extent determined by its power components alone, an important part of the dynamics of modern vehicles is shaped by real-time software, distributed computing and ...
متن کاملDistance protection closed-loop testing using RTDS
This paper presents a distance protection test procedure by applying the Real-Time Digital Simulator (RTDS) of a power system. RTDS is a tool to design, develop, and test power-system protection. The RTDS enables real-time computation of electromagnetic phenomena with a calculation time step of even 50μs. The hardware allows the import and export of many signals from the simulator to an ext...
متن کاملA Microcomputer-Based Simulator for Digital Control Systems
A microcomputer-based simulator for digital control systems is proposed. The proposed simulator is a hybrid system in which the plant is simulated by conventional method of analog computers and other parts of the system including generation of input signal is performed digitally, using a Z-80 based microcomputer. To overcome the difficulty of programming in assembly language, and at the same ti...
متن کاملA real-time recursive dynamic model for vehicle driving simulators
This paper presents the Real-Time Recursive Dynamics (RTRD) model that is developed for driving simulators. The model could be implemented in the Driving Simulator. The RTRD can also be used for off-line high-speed dynamics analysis, compared with commercial multibody dynamics codes, to speed up mechanical design process. An overview of RTRD is presented in the paper. Basic models for specific ...
متن کاملModelling of a Diesel Engine Common Rail Injection System
This paper is devoted to the modelling of a Diesel Common Rail Injection System. The objective is twofold : to build a simulator which will be used later for the rail pressure control scheme validation, and to get linearized models for control design. A mathematical model, based on physical equations is developed and used as a simulator. Then time responses of the rail pressure of a real engine...
