Abstract :
In this paper, coefficient diagram method (CDM) is used to design controller for two-input two-output (TITO) processes. The interactions between the loops are minimized by using the conventional decoupler design method; then, decentralized CDM controllers are designed for the process and decoupler blocks. Several examples are presented to illustrate the effectiveness of the proposed method and compared it with existing ones. It is shown that CDM design is more stable and robust whilst giving the desired time domain performance.
