Özet

In this paper, the coefficient diagram method (CDM) is used to design a controller for stable processes with a time delay to achieve high performance. For this, first order plus time delay (FOPTD) and second order plus time delay (SOPTD) models are used. The explicit tuning formulae of the controller using the polynomial representation are presented based on closed-loop pole-allocation strategy according to the FOPTD and SOPTD plant models. The results are compared with other commonly available tuning methods. It is shown that the CDM control system is more successful in view of the stability, time response, disturbance rejection and robustness properties of the closed loop system.
