Abstract

In this paper, the authors have aimed to develop a control technique using Sliding Mode Control (SMC) and Dynamic Sliding Mode Control (DSMC) for a pH control plant. This pH plant is also subjected to a Proportional Integral Derivative (PID) controller. The pH control process involves a prototype model in which acidic and alkaline streams are mixed into a Continuous Stirred Tank Reactor [CSTR] in proper proportions to control the pH of the plant. The control mechanism involves control of the flow rate of the acid and alkaline solutions. SMC and DSMC are the types of Variable Structure Control (VSC). As the neutralization process is non linear, VSC serves as a better solution. Also PID control is implemented on this process and the results are compared. The unique feature of this paper is that all the control methods are implemented using LabVIEW software. LabVIEW stands for Laboratory Virtual Instrumentation Workbench. The programming is done with this software and is applied to the prototype model. The results of PID, SMC and DSMC are compared and it is found that VSC controllers are better suited than PID controllers.
