Description
Summary:This paper presents a logical continuation of our work by proposing the utilizing of ARX model by using pseudorandom binary sequence (PRBS) as the input signal and temperature as an output. The down-flowing steam distillation column developed in this work is intended for extracting the essential oil by steam distillation technique to improve the quality of output yield and get high quantity of essential oil as compare to the conventional steam distillation. The LabView 2010 was used to design the block diagram and front panel for controlling the data collection. The modeling is done by using model order 1 and model order 2. From this analysis the data collected show that the best fit from modeling using ARX model is greater than 98% for both model orders. From the result, ARX model is adequate to model the behavior of heating process is closed to the real system.
