Abstract

Coefficient Diagram Method (CDM) is the one of the most effective control design methods in literature. It gives control systems that are very stable and robust, system responses without overshoot and very small settling time. The CDM, resolve the classical control problem after selecting a few meaningful design parameters and by automatically determining a target characteristic polynomial for the closed-loop system. The classical CDM design was originally only performed in s-domain. But since, all industrial controllers are digital controllers, it is necessary to improve a digital controller based on CDM. In this paper, the Digitalized Coefficient Diagram method is introduced (D-CDM) and this new digital controller design method applied to different control systems. The very satisfactory results obtained by the new design method are discussed in details.
