hi everyone,

in the picture i uploaded you can see my closed loop model for a dynamic system.
im trying to get the transfer function between the input signal Va to the output signal Phi , while considering all the feedbacks.
when i do it by the model linearizer app or the control system designer i get strange bode plots and wrong transfer functions.
so i would like you to help me understand how can i do it correctly plese.
the seconed question is how can i get the same closed loop transfer function on simulink script by using feedback command.
thank you!hi everyone,

After converting my data into a combined datastore, I tried training a deep neural network with the architecture shown below but the error " Error forming mini-batch for network input "sequence_prop". Data interpreted with format "CBT". To specify a different format, use the InputDataFormats option.
Error in netPaperv4 net = trainnet(dsTrain, net, "mse", options);

Here a datastore preview: 1×2 cell array
{[-0.2964 -0.2723 0 0.3049 0.1613 -0.9312]} {[2.2746]}
I want to combine three different sequence inputs (the goal is time series forecasting, not image classification: my inputs are all time-depending sequences) : two of size 1 and the other of size 4 to predict a single output (size 1).
Can anyone help me solve this?

Basically, I am trying to write a script to be able to find the value 999 in my table, and add the nearest possible values above and below the 999.
For example, if 999 were a value in row 10, column 4, I would want to add 12+18, then divide by 2, and then replace that 999. If 12, 16, 18 were all set to 999, I would want to add 10 and 22, then divide by 2. Then replace 12, 16, 18 all with 16.
