ABOUT A SOLUTION FOR IMPROVING QUALITY OF THE CONTROL SYSTEM WITH DELAY USING EXTRAPOLATION CONTROLLER AND DIGITAL PID CONTROL LAW

Abstract

This paper presents a solution to improve the quality of the control system
with delay, using digital PID controller and apply the Smith extrapolation
controller model, in which the control signal depends not only on the
instantaneous value of the error between the output and the input signal but
also on the change of the control signal during the delay time of the system
when controlling the process so that increasing the stability, reducing the value
of the maximum adjustment, increasing the impact quickly and improving the
accuracy in the setting state of the system.
