The above article was first published online with errors.
The sliding surface proposed in Equation (51) in our study consists of two parts. Whereas the first part is based on the sliding surface definition in (Furat and Eker, 2014), the sliding surface is proposed by making it dynamic adding H$(U(s)) in the second part where H is a constant number and U(s) is the integral of the control input given in Laplace domain.
Although the first part of the Equation (51) was based on the definition in (Furat and Eker, 2014), citing the manuscript was inadvertently omitted. Therefore, the following correction is required.
The first column on the page 1772: Last paragraph on line 12–13 was revised as follows:
“The PID sliding surface-based second-order sliding surface (Furat and Eker, 2014) is selected as base equation to make the sliding surface dynamic as follows:”
The authors apologise for this error.
