Since deriving a new model for tumor model is substantial, introduced system identification algorithms are used in order to estimate parameters of a specific nonlinear tumor model. Besides, in order to estimate tumor model a collection of output and input data is taken from the nonlinear system. Apart from that, effectiveness of the identification algorithms such as convergence rate and estimation error is depicted through various tables and figures. Finally, it is shown that the two stage approach has higher identification efficacy.</p> 2024-02-20T00:00:00+00:00 Copyright (c) 2024 Kiavash Hossein Sadeghi, Abolhassan Razminia, Abolfaz Simorgh
