RANDOM SAMPLING REMNANT THEORY APPLIED TO MANUAL CONTROL.

Abstract

The theory comprises stochastic finite-dwell sampling among displays with continuous control output based on cardinal reconstruction theory. Random sampling remnant theory introduces the notion of stability in the mean-square sense in the operator's closed-loop tracking performance. A related regression of adopted crossover frequency is shown to be sensitive to the controller's sampling remnant. Foveal or parafoveal finite dwell sampling and intersample control output reconstruction suppress sampling remnant. A suppressed remnant will enable the operator to adopt ratios of sampling-to-crossover frequency more nearly approaching the lower bound predicted by the generalized sampling theorem. Two examples illustrate the practical application of the theory to displays for manual control. The influences of finite dwell and intersample reconstruction suggest that sampling remnant may offer a powerful practical measure for trading off the number and types of displays in a multiloop control situation.
