Adaptive Leader-Follower Formation Control of under-Actuated Surface Vessels with Model Uncertainties and Input Constraints

The authors wish to make the following corrections to this paper [1].

In Figure 16, if you refer to the text of the paper [1], you notice that the second section Y-axis name of this figure is $\ln \left(\cos \mathrm{h}{e}_i\right)$ and is different form the first section Y-axis name $\left(\tan \mathrm{h}\left(e_i\right)\right)$. During the simulation in MATLAB, the names of both Y-axes were mistakenly written in a similar way, which we corrected it; thus, Figure 1 needs to be corrected as follows:

and should be replaced with
