An outline of Advanced Process Control and self tuning techniques on PLC background

Abstract

Advanced Process Control techniques contain software packages for an advanced control based on mathematical methods. A self tuning function of regulators has become a standard function of distributed control systems.Most of nowadays digital industry regulators and PLCs are provided with some kind of the self tuning constant algorithm. The practical part of the paper deals with design of the control systems which contain self tuning regulator.Control system with PID Self Tuner and with the visualization is designed. There is a description of an implementation of the PID regulator as a function block which can be also used for extension control functions. Control systems for relay and moment self tuner with visualizations are also designed.

Analysis of dataflows within industrial control system design

“…The aim of these approaches is an effective design of a high quality application from the perspective of the structure, readability, extendibility, level of hidden faults, efficiency of commissioning etc. [3], [4] A typical example of control application design is so called V-model which is used for standard control applications as well as for functional safety control applications. V-model is a graphical representation of a process system design used from facilitating the understanding of complex systems to detailed description of the various stages of the system life cycle.…”
