Prelude In this brief article I will attempt to give a fairly personal and retrospective view on the recent developments in the theory of sampled data control systems The emphasis is upon how I came to discover a new function space framework currently called lifting for sampled data systems and how this notion helped to clarify certain issues in the study of such systems It was a fairly cold da...

This paper studies the problem of quantized feedback control for sampled-data systems which employ a quantizer to transmit feedback signals at a given sampling rate. The so-called static (memoryless) quantizers are considered. Given a continuous-time system, the design objective is to stabilize the system or to achieve certain performance using the coarsest quantization density. We study the po...

This paper deals with the problem of sampled-data gain-scheduling control design for affine quasi-LPV systems. As implementation is based on sample-data and its update occurs only at specific sampling instants, state-dependent scheduling functions controller are piecewise continuous. characteristic causes a mismatch between system model parameters, namely asynchronous respect to plant during in...
