Abstract

ABSTRACT: This paper addresses the output feedback control design problem with limited data-rate constraints. These communication constraints may affect the transmission of control signals or measurements, giving rise to different models, depending on the interconnection architecture. The closed-loop system composed by plant and controller can be modelled as a Hybrid System whose stability and H 2 performance can be determined in terms of necessary and sufficient Linear Matrix Inequalities. However, for the design of the appropriate feedback gains, those conditions become non-convex and we propose an approach to obtain satisfactory solutions. Numerical examples are included.
