Abstract :
Over the past five years, there has been substantial interest in the use of generalized sample hold functions for control. The authors use a tool that is novel in this context, namely amplitude modulation theory. They employ this tool to analyze the quantitative and qualitative features of the intersample behavior in a frequency domain setting. This offers new theoretical and practical insights into the method. The conclusion is that the approach has inherent and unavoidable difficulties which make its practical use questionable
