PID, SMC and DSMC techniques of a prototyped Split Range Plant using LabVIEW

This paper deals with the level control of a prototyped Split Range Plant Process. The conventional PID Controller is initially applied to the process and the results are obtained. As the system takes a large settling time the following two controllers are also implemented. Apart from lowering the settling time, to increase the robustness of the system Sliding Mode Control (SMC) and Dynamic Sliding Mode Control (DSMC) are applied to the same system and the results are compared. To make the system more user friendly the whole programming is done in LabVIEW (Laboratory Virtual Instrument Workbench) software. This software is based on graphical programming technique. The objective of this paper is to present the response of all the three controllers on the prototype split range plant.
