Abstract

Hybrid systems are real-time systems that allow both continuous state changes over time periods of positive durations and discrete state changes in zero time. Being an important subclass of hybrid systems, linear hybrid systems are usually modeled using linear hybrid automata. Linear hybrid automata are undecidable in general, but for a subclass of linear hybrid automata called positive loop-closed automata, the satisfaction problem for linear duration properties can be solved by linear programming. To support automatic checking of linear hybrid automata for linear duration properties, a tool named LDPChecker implementing the checking algorithm has been developed. The tool LDPChecker can identify positive loop-closed automaton and perform checking on it. Its key features include its ability to check real-time and hybrid system for many real-time properties including reachability property, and to generate diagnostic information automatically.
