Parametric identification of multivariable industrial system using left matrix fraction description

Abstract EN

his paper we are applied the theory ofLinear Multivariable system identification based on the Left Matrix Fraction Description (LMFD) to find a approximate mathematical model using a recent measuredinputs outputs real data ofturbo compressorgas turbine.

The approximate modelis obtained via the MIMO Least Square(MLS) estimator based on the Left MFD, to select the best model order we check each one with two validation criteria AIC and FPE, finally we acquired stable valid and reliable model in Multivariable Block Observable canonicalForm
