Robust Pid Controller Design for Coupled-Tank Process Using Labreg Software
نویسندگان
چکیده
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). Robust controller is designed in two ways. The first approach is performed with the Edge Theorem and the Neimark’s D -partition method for the affine model and the second one is performed with the modification of the Neimark’s D -partition which ensures desired phase margin.

متن کاملLiquid level control of coupled tank system using Fractional PID controller
In process industries PID controllers are used more. In PID controller we have three parameters for tuning and tuning is done by using Ziegler-Nicholas method. In this paper we used fractional PID controller for coupled tank system and by using a tuning method for getting required response. First used zieglar-nicholas and Astrom-Hagglund method for tuning, then derived two non-linear equations ...
