Abstract :
A framework for developing hierarchical control systems consisting of layers that group transformation types, the tools to help implement the layers and validate timing properties, and the mechanisms for communicating among layers is discussed. The layered framework supports the design and implementation of control systems with both continuous and discrete components, and is suitable for integrating symbolic and numeric computations in a range of applications. Two applications of the framework-an elevator control system and driver support system-are described.<>
