- Stability problem in NARMA identification
- -----------------------------------------
-
- I'm doing a nonlinear system identification of the follow process:
- Y[n]=f{Y[n-1],Y[n-2],....X[n],X[n-1],...}
- In the learning phase of open-loop I can reach avery small error criteria.
- From the open loop learning I can see that the system is learning on the
- wright direction, when I close the loop I have stability problem.
- I'll be interested to hare any ideas or solution to this problem (articles
- and books).
-
- thanks
