Abstract
The authors demonstrate that the parameter estimates of the output error identification algorithm are not necessarily globally bounded when the prediction error is corrupted by an arbitrarily small disturbance. The cause of the parameter estimate drift to infinity is an input which can be interpreted as an open-loop control to an unstable system. The disturbance could actually be vanishing
