Identification of a Class of Non-integer Order Rational Models

摘要

Main contributions include: (1) A non-integer order rational model structure is presented with justification of more general form for non-linear rational models.(2) An Enhanced Back Propagation (EBP) algorithm for parameter estimation of a class of non-integer order rational models is presented.Comparing with general BP algorithm,the convergence rate of the proposed algorithm is improved.The convergence of the presented algorithm is proved.Also,the effectiveness of non-integer order rational models and the EBP algorithm is initially demonstrated by a simulation case study.
