Analysis and control with performance of piecewise affine and hybrid systems

In this paper we investigate some analysis and control problems with performance for discrete-time hybrid systems in the piecewise affine form. By using arguments from the dissipativity theory for nonlinear systems, we show that H/sub /spl infin// analysis and synthesis problems can be formulated and solved via linear matrix inequalities that take into account the switching structure of the systems. Moreover, such procedures can be generalized in order to solve both robust control problems and analysis/synthesis with other performance indices like the generalized H/sub 2/ norm.
