Hybrid control systems are a combination of real-time control law and discrete-state logic. This paper describes how a Development Framework for control systems software has been adapted so that it may also handle discrete events such as mode switching. The Framework provides a highly automated path from a controlengineering specification to a distributed system implementation. Simulink, an extension to Matlab, is used to specify control laws, and a statecharts tool, Statemate, is used to specify and model discrete-state components. The design phase of the Development Framework supports the integration of the two sets of specification. An inverted pendulum control system is introduced as a simple example of a hybrid system implemented using the Framework. The translation of statecharts to dataflow notations is described for the example system. General translation rules are also presented.
Formal verification of safety and timing properties of engineering systems is only meaningful if based on models which are systematically derived. In this paper we report on our experience using switched bond graphs f...
