Abstract

Wireless Network Control System (WNCS) has received considerable attention with advances in control and communication technologies. This paper presents the stability analysis of real time PI controller design and Smith Predictor control strategy for the compensation of assumed delay in the plant. Mathematical modelling of the plant is obtained and the parameter estimation of the traditional controller design is obtained by IMC tuning relationship which is a comprehensive model-based design method. Real time laboratory test demonstrates the mobile based wireless control of the plant with the help of the application Data Dashboard for LabVIEW that enables the creation of custom user interface that can monitor and control LabVIEW applications remotely. Comparative chart for the performance of the plant with and without wireless network for the various control designs is also made.
