By type, it is segmented into feedback artificial neural network, feedforward
artificial neural network, and others.
Then on the follow-up, especially important here is what I call a feedforward
, where they ask for ideas which is much more positive.'
An in-cylinder pressure feedforward
controller was designed firstly.

For the objectives of this nature, feedforward
networks are reasonably suitable.
control architecture is shown in Figure 4.
What needs to be specially mentioned is that, considering the phase delay in the sampling, grid voltage feedforward
sampling value [U.sub.st] is obtained by multiplying the fundamental RMS of [U.sub.s] with cos [theta].
In the experiment, we choose feedforward
backpropagation neural network and cascaded feedforward
backpropagation neural network, in which the hidden layer and output layer of the feedforward
BP neural network are only affected by the previous layer.
With each model change, the controller must be recalibrated and redeployed, which may involve adjustments to both the feedforward
and feedback portions of the controller.
In order to approximate f* we applied a deep feedforward
network with six hidden layers to our problem domain using the TensorFlow framework .
Wiener models are also used, for example as a robust nonlinear internal model control of stable Wiener systems , or block-oriented feedforward
control with demonstration to Wiener modelling , or modelling of memristor-based chaotic systems using nonlinear Wiener adaptive filters .
The feature vectors are then fed to a feedforward
