Black-Box Modelling of a DC-DC Buck Converter Based on a Recurrent Neural Network

Abstract: Artificial neural networks allow the identification of black-box models. This paper proposes a method aimed at replicating the static and dynamic behavior of a DC-DC power converter based on a recurrent nonlinear autoregressive exogenous neural network. The method proposed in this work applies an algorithm that trains a neural network based on the inputs and outputs (currents and voltages) of a Buck converter. The approach is validated by means of simulated data of a realistic nonsynchronous Buck converter mod… Show more

“…In refs. [15][16][17][18][19][20][21][22], various adaptive-based controllers are designed as follows: adaptive neural network-based controllers, adaptive sliding mode controllers, adaptive Lyapunov-based control, and adaptive predictive controllers. The main benefits presented by these methods are effective to control in ill-defined systems, robustness toward load uncertainties, faster dynamics performance, and better external disturbance compensation.…”

“…In addition to the introduction of AI in the EV market, DC-DC converter controllers based on NN supervised/unsupervised learning and reinforcement learning techniques are powerful tools concerning the noise and uncertainties [47][48][49][50]. AI networks were used to identify a black-box converter model in [51]. The neural network predictive controller (NNPC) that combined the advantages of both the NN and MPC was applied to the buck converter in [47], which investigated the accuracy during start-up and during the reference voltage variation.…”

“…In [17] a LSTM-NN was applied to model the transient behavior of a DC-DC power converter used in mild hybrid electric vehicles. In [18] a recursive artificial neural network, in this case a nonlinear autoregressive exogenous neural network (NARX-NN) was applied for reproducing the behavior of a DC-DC buck converter at the expense of the time required to train the network. Wavelet artificial neural networks (WA-NNs) have been also applied for this purpose.…”
