Abstract

The control of liquid level in tank is a basic problem in process industries. The conical tank level process is
considered to be a non-linear process. The control of conical tank is presenting a challenging problem due
to its non-linearity. The modeling aspect of conical tank is discussed in this paper. The piecewise response of
the system is studied and the gain and time constants for the different regions were tabulated. A structure of
wiener based nonlinear controller is developed using LabVIEW and it is implemented in real time. The
response of the wiener based nonlinear controller is compared with the classical PI controller.
Key words: Nonlinear PI controller, Wiener Model, Conical Tank
