Abstract
A fully linearizable single-input-single-output relative-degree n system with an output time delay is considered in this paper. Using the approach of Padé approximation, system center approach, and second-order sliding-mode (SM) control, we have obtained good output tracking results. The Smith predictor is used to compensate the difference between the actual delayed output and its approximation. A second-order supertwisting SM observer observes the disturbance in the plant. A nonlinear example is studied to show the effect of this methodology.
