Modeling and simulation of hybrid systems

Previous research in the area of modeling and simulation of hybrid systems led to the development of a general hybrid systems modeling language (HSML), part of which was implemented in a preliminary way by extending MATLAB. This paper describes the second phase of algorithmic implementation of the HSML ideas and language constructs for dealing with state-event handling and model structural changes in continuous-time system components. Specifically, the standard MATLAB model framework and integration algorithms are extended to support these phenomena. An example is presented to show the efficacy of these extensions within the MATLAB environment
