Abstract
Web-based simulation of hybrid automation systems has attracted much attention. However, most available modeling approaches usually result in unnatural and complex models as both discrete logic and continuous behavior are involved. Based on the multi-paradigm modeling concept, this paper extends the traditional discrete statechart to model the continuous dynamics in a hierarchical and natural way. Furthermore, a Java-based kernel is developed to implement the simulation of the extended models. An application of Web-based simulation for a three-axis motion control system in the context of e-automation is provided to illustrate the proposed modeling and simulation approach.
