Data Missing and Make-up Work Studies over a PIDn Networked Control System

摘要

This paper studies the data missing and make-up work over a PID{sub}n networked control system (NCS). We start with the simplest method by replacing the missed data with the previous one, then move to the linear interpolation and the numerator polynomial method. The study shows that these data make-up work can be rewritten in one formula. For a given PID{sub}n controller, different data make-up work only give different parameter and the system performances will be the same. This conclusion is verified in our simulations.
