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

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.
