- Hi,
-
- We have been working on using the feed-forward NN to emulate the
- dynamics of chemical processes. It works well for simple processes but
- fail to learn the process with non-linear time-delay, for example
-
- y(t) = u(t+10-int(y(t-1)/.1)*0.2 + y(t-1)*0.8
- where 0<y(t)<1.0.
-
- This process has time-delay that is a function of the output. We have
- tried using feed-forward net to learn the dynamics of this process
- without any sucess. Can anyone give us some advise on this. Thank you
- in advance.
-
- Kim Hock.
