A COMPARISON BETWEEN TWO FRACTIONAL MULTIMODELS STRUCTURES FOR RAT MUSCLES MODELLING

Peroneus digiti quarti and peroneus brevis muscles responses of the rat are studied for 10 Hz pulses stimulations. A comparison between two multimodels structures is presented. These multimodels include fractional sub-models. The multimodels allow distinguishing contraction and relaxation phases for identification. Fractional orders used in the sub-models lead to minimize the size of transfer functions. The present study develops the multimodels structure earlier established, by including variation functions of extra parameters for IIA and IIB fibres and to explain muscle response for Motor Units (MU) stimulations at 10 Hz. The multimodels explains rat striated muscle responses, and so, allow its inclusion in a future muscle computer model.
