Abstract: Component hybrid dynamic nets (CHDNs) are a graphic model for hybrid dynamic systems, which allow every component of the hybrid system to be individually represented. On the basis of this methodology, a software tool dedicated to electrical engineering simulations has been developed. Thus, the aim of this paper is to present a brief review of the model structure and to describe the developed software called SimRDH. In order to show the applications of this software tool, a hydraulic system, a mechanical system, and finally, an elevator system powered by supercapacitors have been studied.
Abstract: The Component Hybrid Dynamic Nets CHDN is a graphic model for hybrid dynamic systems. The CHDN allows an individual representation of every component in the hybrid system. On the base of this methodology a software tool dedicated to the electrical engineering simulation has been developed. So, the aim of this paper is to present a brief review of model’s structure and to describe the developed software which has been called SimRDH. The software is used to simulate a permanent magnet synchronous motor supplied by a pack of supercapacitors. The obtained results are encouraging especially in the development of Electrical Vehicle Simulator.
Abstract: The Advanced Component Hybrid Dynamic Nets ACHDN are a graphic model for hybrid dynamic systems, which allow every component of the hybrid system to be individually represented. The ACHDN is the ameliorated version of CHDN models. Thus, the aim of this paper is to improve the model and proposes new kind of components to deal with modelling thermal systems. In order to show the applications of this model, a simple thermic conduction system and a control thermic system have been studied. All simulations in this paper are done with SimRDH software.
Abstract: Fuel cell with supercapacitors is a multi-physical system which, in association with converters, becomes hybrid. To model this complex system, different proposals have been made in literature. In this paper, Component Hybrid Dynamic Nets (CHDN) are used to model this system. CHDNs are a graphic model for hybrid systems, which allow each component of the hybrid system to be represented; moreover a novel software for hybrid modelling, SimRDH, is presented which allows each component of the system to be well represented, no matter if it is continuous or discrete.
Abstract: The new constraints in vehicle design for personal mobility are the development of a non-polluting and high safety vehicle. This is the consequence of increasing road traffic and climatic environmental problems. Like solution of these problems, the vehicle with electrical traction has been contemplated. The pollution is strongly decreased and the electric traction gives the possibility to achieve accurate and quick control of the distribution torque. This paper presents a traction control system of an electric vehicle (EV) based on the energetic macroscopic representation (EMR) and its maximum control structure (MCS). The simulator ELEVES has been used to simulate the studied system. Finally, in order to validate the simulation results, a comparison between the results obtained by ELEVES and those obtained by Matlab/Simulink software tool has been included.
Abstract: This paper presents three degrees of freedom dynamic model for an electric vehicle with two in-wheel motors placed at the rear wheels. Both dynamic and electrical modeling have been considered in this work. So, after giving the mathematical forms of this models, their implementation under SimRDH software is also presented. The obtained simulation results, showing the well operating of the proposed models, are included.
Abstract: Vehicle simulation software is essential to vehicle design and development. Most current vehicle software simulations, however, require that component be specified prior to running the simulations. This works well if the user’s goal is to gain insight into a particular design. Therefore, the simulator must be flexible enough to add new component and use different level of accuracy. This paper presents the first version of a new software tool. It was designed as a tool to assist in developing technologies for Electric Vehicle (EV). The ELEctric VEhicle Simulator (ELEVES) is currently being developed as a research project in the University of Technology of Belfort-
Montbeliard (UTBM) on our laboratory of Systems and Transportations (SeT). This simulator is deduced from SimRDH tool that uses the Component Hybrid Dynamic Nets (CHDN) to extracting a system of equations. As application, we are used our software tool to modeling and simulation of four motorized wheels electric vehicle.
