Question on ANN training
显示 更早的评论
I plan to use the feed forward back propagation ANN to train the data I have obtained from the PV system from SIMULINK. I have set my input data as the PV power and the output as the duty cycle values. At the end of this, I plan to replace my MPPT algorithm with this ANN which will predict the duty cycle by attaching it into a MATLAB function block in SIMULINK. However, I am getting an error with my training which says 'not between 0 and 1'. The image below shows the parameters I have set. I have attached my input and output data too.
Thanks!

From the error statement (“not between 0 and 1”) which you are getting during training, it seems that your input data (PV Power) needs to be normalized in the range (0,1) before feeding to the ANN. I have checked the "PVPower.mat" file and data in this file are not normalized. Normalizing input data before training also enhances the performance of the network.
To normalize in that range you can use normalize function.
N = normalize(PVPower,'range')
For more details on normalization you can follow this link:
