Modeling of heat transfer process with the use of non integer order, discrete, transfer function models

摘要

The paper is intended to present a possibility of modeling a heat transfer process in one dimensional plant with the use of new, non integer order, discrete models. The proposed models have the form of hybrid transfer functions, containing both integer and non integer order parts. The integer order part represents a pure delay, the non integer order part is modeled with the use of CFE approximant. The proposed models were compared to step responses of real experimental plant with the use of typical MSE cost function. Results of experiments show that a good accuracy can be achieved for relatively low order of model.
