LICS - Language for Implementation of Control Systems

Elmqvist, Hilding (1985) In Technical Reports TFRT-3179.
Abstract
This report describes a language and an interactive environment, called LICS, for implementation of control systems and dynamic modelling. It used graphics for representation of the structural properties: hierarchical decomposition, interconnection structure, and structure of the interfaces. The decomposition and interconnection structures are described by block diagrams. Low level modules are described by equations. <br><br> Much effort has been devoted to the design of an integrated language both for analog control and logic control. It resulted in powerful module and interconnection concepts that make it possible to develop libraries of modules for different applications. The user can build systems from such libraries... (More)
