Research in Multirate Estimation and Control--Optimal Sample Rate Selection

摘要

A new algorithmic methodology for sample rate selection in multirate digital control design is developed. The methodology is based on optimizing the random disturbance rejection properties of a closed-loop multirate control structure under a computational constraint. The formulation and mathematical development of the multirate control design and sample rate selection procedure are presented; the sample rate selection technique and properties of the resulting controllers are demonstrated through aircraft control examples.
