I have to predict the duty cycle of the single input multiple output converter. I have to use the look up table for that. How do you create a look up table?
You can use train a machine learning algorithm, regression type which will learn the look at table from training example. If you know the relation between your inputs and output, you can decide which method is the most adequate (linear regression, logistic regression, Neural Network, Gaussian Process).
I think you should first formulate the relation between input and output from a given set of data. Then, you can use the same formula to setup a complete look up table.
It is interesting to start the problem resolution from the output signal features then formulate the duty cycle search as an optimization problem to predict the list of the suitable values to take place int the look up table you are looking for.
