HYSTAR: a toolbox for hierarchical control of piecewise linear hybrid dynamical systems

Describes a Matlab toolbox for computational analysis and hierarchical controller synthesis of piecewise linear hybrid dynamical systems. The analysis and design are based on computation of predecessor operator and backward reachability analysis. Both static specifications that do not change as time progresses and dynamic specifications that include sequencing of events and eventual execution of actions are considered. Control design is implemented using finite automata and linear programming techniques. A temperature control system is used for illustration through out the paper.
