Investigate the impact of information delay to control quality
A problem of the investigate the impact of information delay in communication channels "regulator - object" and "object - regulator" in process control systems is examined. A mathematical model of control system that takes information delay into account, and methodology of the study is proposed. The results of numerical simulation is presented. The effect of information delay on the integral performance indices of step responses in the control system is shown. Recommendations regarding for the allowable values of information delay and the arrangements for its reduction.
