Modelling of an Air Handling Unit: A Hammerstein-bilinear Model Identification Approach

Black-box modeling of residential HVAC system and comparison of gray-box and black-box modeling methods

“…According to the review of modeling methods for HVAC systems in [36], the researchers have developed several methods such as white-box models [37,38], black-box models [23,32,[39][40][41][42][43] and gray-box models [44][45][46][47] to model the behavior of the HVAC systems. The white-box models require the understanding of the system physics and use the manufacturer supplied parameters for modeling the system dynamics.…”

Parameter Estimation of Hybrid Fractional-Order Hammerstein-Wiener Box-Jenkins Models Using RIVCF Method

“…where the over-parametrised polynomialB(D β ) and vector F(t) are given in (8) and 9, andḡ i (t) = g i (x). Since measured data is used for parameter estimation, the output of the model in (12) is considered to be corrupted by a noise process.…”

“…(viii) Repeat steps (i) to (vii) until the sum of the squares of the differences betweenθ l−1 andθ l is significantly small such as 10 −4 or, for example, five iterations. Whilst there would appear to be an issue associated with the estimates of the over-parameterisedB(D β ) in (8), wherebyb s and b s are combined within one vector, it was shown in [21] thatb s can be directly obtained from B i (D β ) in (8) by using:b…”

“…In energy storage systems, the battery impedance model has been improved by introducing a Wiener static nonlinearity to the ordinary equivalent circuit model [6], [7]. Hammerstein models have also been employed to represent the air handling unit of large heating ventilation and air conditioning systems [8], where it is principally used to describe the nonlinearity introduced by the valves. The model that uses a nonlinear block both preceding and following a linear dynamic system is called a Hammerstein-Wiener model [9], [10].…”

Parameter estimation of the fractional‐order Hammerstein–Wiener model using simplified refined instrumental variable fractional‐order continuous time

“…In the automotive industry, the battery impedance model is enhanced by introducing a Wiener static non-linearity to the ordinary equivalent circuit model [24]. Hammerstein models have also been employed to address bilinear models to represent the air handling unit of large heating ventilation and air conditioning systems [25], where it is principally used to describe the non-linearity introduced by the valves.…”
