The Advances in Mechanical Engineering Editorial Office became aware that the peer review process organised by the Guest Editors of the Special Collection Advanced Control and Analysis of Mechatronics Systems with Modelling Uncertainty did not meet the journal’s usual rigorous standards of peer review. Due to this, all articles in the Special Collection were re-reviewed by a new set of independent referees.

Based on the feedback from the new independent referees, the following corrections are to be made to the above-referenced article.

With reference to Equation (23), the definition of ${\tilde{D}}_p$ causes misunderstanding and should be modified. The sentence “Defining ${\tilde{D}}_p$ as the error between the real lumped disturbance and the estimation value” is modified to “Defining ${\tilde{D}}_p$ as the error between the real lumped disturbance and the compensation term”.

From Figure 2, the term $g_n(s)e^{-{\theta }_{n}s}{\overline{D}}_f(s)$ but not ${\overline{D}}_f(s)$ is in the same place with $D_p(\text{s})$ . ${\overline{D}}_f(s)$ is the estimation value and $g_n(s)e^{-{\theta }_{n}s}{\overline{D}}_f(s)$ is the compensation term.
