چکیده مقاله:
Identifying a system and estimating a
model based on Input-Output data is a very important
process because many engineering method and
solutions depend on the model. In this paper, the
problem of nonlinear Takagi-Sugeno (TS) fuzzy
system identification of the HIV infection disease is
investigated. TS fuzzy system with input-output
representation is considered and the parameters of
the consequent part are computed based on the least
square (LS) and gradient descend (GD) methods.
Meanwhile, Gaussian fuzzy membership functions
are utilized in the premise part. Furthermore, based
on the practical restrictions and response of the HIV
disease, a proper pseudo-random binary sequence
(PRBS) input signal is proposed. Numerical
simulation results show the accuracy of the TS fuzz
