ROBUST PID CONTROLLER DESIGN FOR COUPLED-TANK PROCESS USING LABREG SOFTWARE

The paper deals with the design of the robust PID controller for real uncertain Coupled-Tank process in the frequency domain. Only the first independent tank is considered (single-input single-output system). In robust controller design procedure the Edge Theorem and the Neimark's D -partition methods for the affine model are included. For identification and control of Coupled-Tank process LABREG software is used.
