Basics of Coefficient Diagram Method
2021In this chapter, the fundamental properties which are necessary for CDM design will be presented. In Mathematical Relations, definitions of symbols and their basic relations are briefly discussed. In Coefficient Diagram, the way to draw coefficient diagrams is first introduced and then the interpretation of the coefficient diagram is presented.

IFAC Proceedings Volumes, 1998 Abstract A controller design method, called Coefficient Diagram Method (CDM), is introduced. By this method the simplest controller to satisfy the specification can be designed efficiently. The designer can design the controller and the characteristic polynomial of the closed-loop system simultaneously taking a good balance of stability, response ...

Robust control synthesis using coefficient diagram method and µ-analysis: an aerospace example
International Journal of Dynamics and Control, 2018This paper develops a structured controller synthesis method which satisfies robust stability and robust performance. In the proposed method (µ-CDM), coefficient diagram method (CDM) is employed to synthesize a structured controller and µ-analysis is used to evaluate the robustness of the controller.

Design of a robust controller for any control system is of paramount importance in the field of control system design. Despite parameter variations, the controller has to generate signals to enable satisfactory performance of the system. One of the recent developments of the robust controller design methods is the coefficient diagram method (CDM ...

Introduction to Coefficient Diagram Method
IFAC Proceedings Volumes, 2001Abstract We introduce a linear controller design method, called the Coefficient Diagram Method (CDM), which is a kind of model matching approach. In this paper, we have especially focused on the main role and characteristics of specific design parameters γ i , and τ , which are defined by only coefficients of characteristic polynomial.

Digital design of Coefficient Diagram Method
2009 American Control Conference, 2009Coefficient 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 ...
