Quantized output regulation of minimum-phase linear uncertain systems

This article investigates the robust output regulation problem of a class of minimum-phase linear uncertain systems subject to limited measurement information. A novel dynamic quantized output feedback control law together with a hybrid quantized feedback control policy is developed. By means of Lyapunov analysis, it is shown that the tracking error tends to zero asymptotically in spite of system uncertainties, disturbances, and limited measurement information. In addition, a special case of the main result leads to the solution of the robust stabilization problem of minimum-phase linear systems subject to system uncertainties, disturbances, and the quantized output.
