SimRDH: A Modeling and Simulation Environment With Component Hybrid Dynamic Nets, Elevator Application

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.
