Abstract

Abstract—In networked control systems (NCS) environments
is usual to find restrictions with data-acquisition frequency. If
the control action updating can be faster than the output
measurement, the use of a dual rate controller is a natural
solution. Due to PIDs are useful controllers in industrial
applications, in this paper a dual rate PID controller is
designed splitting a conventional PID into two parts acting at
different sampling rates. Its implementation over a specific
NCS scenario (Profibus DP) is assumed. The study includes a
description of a NCS, the introduction of a dual rate design
methodology for PID controllers and also an analysis that
validates the real implementation using this approach. Finally,
theoretical and practical results are shown too.
