fotf2io

FOTF2IO Identify fractional-order tranfer function as integer-order model

 Usage: [K,L,T] = FOTF2IO(FSPARAM, MODEL, INITPARAMS, OP)
 where
        [K, L, T, Y, TIME] - model parameters [K, L, T] 
                             and original simulation result [Y, T]

        FSPARAM - structure with the following fields (simulation parameters):
              .plant - FOTF plant to identify
              .approx - approximation method, should be 'oust' or 'ref'
              .w - vector with approx. frequencies [wh; wb]
              .N - approximation order

        MODEL - type of model to identify: 'fopdt', 'ipdt' or 'foipdt'

        INITPARAMS (optional) - initial parameters vector with [K, L, T].
                                If not provided, defaults to [50, 50, 50]

        OP (optional) - additional optimization parameters for lsqnonlin
                        defined by OPTIMSET
