MODELLING AND PARAMETER ESTIMATION OF THERMAL PROCESS

Thermal process plays a major role in the field of Mechanical Engineering. In most of the food industries, chemical industries, controlling of Temperature proves to be an important job. Dead time and overshoot are the most vital performance criteria which should handled precisely. First stage is to develop the mathematical model of the thermal process using conventional Process Reaction Curve method. Then the derived models for each temperature ranges are tested by Parameter estimation techniques such as, ARX, ARMAX, BJ and OE methods using System Identification Tool Box in MATLAB. The parameters are estimated based on the final prediction error, best percentage fit and co-relation of residue for the output.
