Abstract
In the paper new non integer order models for speed control in AC motor are proposed. The models have the form of hybrid transfer functions containing both integer order and non integer order parts. Parameters of models were assigned with the use of least square method. The proposed models were compared to integer order transfer function model with delay identified with the use of MATLAB. Results of experiments show that the proposed hybrid models containing fractional order part and integer order part are comparable in the sense of square cost function to reference integer order model and simultaneously they can be simpler to identify and their computational complexity is smaller than reference integer order model.
