JOURNAL OF DYNAMIC SYSTEMS MEASUREMENT AND CONTROL-TRANSACTIONS OF THE ASME, cilt.129, sa.1, ss.121-122, 2007 (SCI-Expanded)
This work presents a commentary, of the article published by Asl and Ulsov (2003, ASME J. Dyn. Syst., Meas., Control, 125, pp. 215-223). We show by an example that their method leads to inaccurate results and is therefore erroneous.
