A practical identification of the opening-and-closing speed dynamics of an elevator door by adapting the fictitious controller to the data

In the present paper, we consider a practical identification of the opening-and-closing speed dynamics of an elevator door. It is important to obtain the actual state of an elevator door for retaining a safety and quick motion. Thus, an identification of the above dynamics is also one of the most important factors for an effective maintenance. However, it is difficult to obtain the actual parameter because of the fact that there are many cases in which an experiment for the identification spends much time and it is undesirable to use a sufficiently excited signal for the identification. These problems should be solved with practical points of view. From these motivative backgrounds, we provide a facile and fast-track identification method for the opening-and-closing speed dynamics of an elevator door. Since the method we proposed here is based on the adaptation of “the fictitious controller” off-line, it is possible to obtain relevant parameters with only one-shot experiment data obtained in the usual operation, which also leads to reduce the cost for the maintenance drastically. In order to show the validity of the result, we also give an experimental result on the identification of the opening-and-closing speed dynamics of the door of an elevator.
