PROJECT TITLE :

Implicit disturbance rejection performance analysis of closed loop control systems according to communication channel limitations

ABSTRACT:

This study investigates limits of implicit disturbance rejection capacity of negative feedback management systems on the basis of communication channel limitations. Disturbance rejection performance of closed loop management structure is evaluated by using reference to disturbance ratio (RDR). Boundaries of RDR performance for stable management system are investigated by using stability boundary locus analyses. For computer-aided system design issues, a graphical design methodology for disturbance rejection PID management system is presented and illustrative examples are shown. Numerical examples show that disturbance rejection management with improved step response performance is obtainable by 2-degree-of-freedom style combining high gain PID management and input prefiltering.
