    This paper presents the method to achieve the design MRAC PID control for fan and plate process. The fan and plate process is another challenged problem for control system design because it has non-linearity characteristic and highly sensitivity for ambient disturbance. Thus tuning of PID parameter performs hardly by root locus or trial & error method. The proposed method presents design methodology of auto-adjustable PID controller using MRAC technique for solving the problems. The adjustable PID parameters corresponding to changes in plant and disturbance will be determined by referring to the reference model specifying the properties of desired control system. Therefore, this technique is convenient to control the process for satisfying the requirement of the system performance. © 2011 SICE.

    This paper presents the approach to design the 2-DOF PI controller with Decoupling for a Coupled-Tank two-input two-output process. The structure of controller design can minimize several undesirable influences from an interaction in TITO Process. The decoupling controllers transform TITO plant transfer function models into SISO form so that 2-DOF PI controller for each SISO model can be designed by Root Locus Technique easily and efficiently. The results from decoupling and controller design can be illustrated by experiments. © ICROS.
