In this paper, the hybrid system consisting of the interconnection of an uncertain continuous-time plant and of a digital controller is considered. The plant is supposed to be affected by matched uncertainties belonging to a wide class. It is also assumed the presence of an A/D converter with bounded quantization errors. A robust controller based on quasi-sliding modes is designed using quantized state information. The behavior of the solutions of the system is investigated, with reference also to the bounds on the quantization size.

Abstract

In this paper, the hybrid system consisting of the interconnection of an uncertain continuous-time plant and of a digital controller is considered. The plant is supposed to be affected by matched uncertainties belonging to a wide class. It is also assumed the presence of an A/D converter with bounded quantization errors. A robust controller based on quasi-sliding modes is designed using quantized state information. The behavior of the solutions of the system is investigated, with reference also to the bounds on the quantization size.
