Research in Multirate Estimation and Control.

Abstract

A new approach to multirate control system synthesis based on optimal estimation and control theory is developed. The new techniques obviate dimensionality problems typical of classically based design techniques and offer a systematic procedure for designing to desired closed-loop specifications. Mathematical derivations of the optimal multirate state estimator, regulator, and proportional-plus-integral controllers are presented. The transient response and robustness properties of multirate systems designed by the present techniques are investigated through examples. (Author)
