Abstract
Over the past 5 years, there has been substantial interest in the use of generalized sample hold functions for control. In this corresponden ce, we use a tool, which is novel in this context, namely, Amplitude M odulation Theory. We 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. Our conclusion is that the perceived benefits come at substant ial cost which makes its practical use questionable.
