Labview Based Tuning of Pi Controllers for a Real Time Non Linear Process
نویسنده
چکیده
The phenomenal growth that has been evidently seen in the last two decades has brought a multifold development in the process industry. The experts have always focused upon the control of the level and other process parameters. In this paper we have chosen a real time Single Spherical Tank Liquid Level System (SSTLLS) for our investigation. The aim of this paper is to compare the design and implementation of Ziegler-Nichols (ZN) and Skogestad’s tuning based PI controllers for the SSTLLS using LabVIEW and NI-DAQmx 6211 data acquisition card. The real time model identification and Graphical User Interface (GUI) are discussed and their PI Controller implementation using LabVIEW are outlined.

Pressure control systems constitute the heart of many process plants. Linguistic modeling and decisionmaking processes like fuzzy and neural controller are very much useful to control the complicated processes. An intelligent control strategy has been proposed and successfully applied to a real time water pressure control system. For the variation of set point change and load disturbance, an in...
متن کاملReal Time Implementation of Model Reference Adaptive Controller for a Conical Tank
Nonlinear process control is a difficult task in process industries. Conical tank level control is one among them. Real processes often exhibits nonlinear behavior, time variance and delays between inputs and outputs. This paper aims at implementing an adaptive control algorithm for a conical tank system. System identification of the non-linear process is done using black box modelling and foun...
