Paper with Unsubstantiated and Wrong Claims about L1 Adaptive Control

We regret to have been informed that a paper with unsubstantiated and wrong claims about L1 adaptive control, that was previously under review, has been accepted for publication in the highly regarded IEEE Transactions on Automatic Control [1]. Although the authors have written the revised paper in a much more professional way, the theoretical claims about L1 adaptive control are still plainly wrong. With great concern, we expect that many genuinely interested researchers will be misled by this paper that is published in a renowned journal. Hence, we urge the readers of this paper to download and read our rebuttal where we explain every single wrong claim in a clear and concise way.

The document can be found here or under the Downloads section.

Additionally another article has been published with similar wrong claims. A document that clarifies the wrong claims made by the authors in [2] can be downloaded here.
