Abstract: In many chemical process industries continuous stirred tank reactor plays a major role to provide the final end product with maintaining temperature, level, flow and pressure at its pre-specified setpoint trajectory. Controlling those physical parameters are difficult because of its nonlinear behaviour. The model has heat and volumetric balances, and a very realistic feature is that instrument, actuator and process non-linearity’s have been carefully measured, for instance, to take account of the volume occupied by heating coils in the tank. Experimental data from step testing and recordings of real disturbances are presented. The model in Simulink and the experimental data are available electronically and some suggestions are given for their application in education, system identification, fault detection and diagnosis. The performance of the CSTH process has improved and the parameters are maintained at their desired level of the set points with minimum Integral Square Error (ISE), minimum rise time, minimum peak overshoot and minimum settling time. The real time plant is interfaced with LabVIEW with NI data acquisition card, Zigbee based wireless data transmission and the experimental results are discussed in this proposed work.
