Abstract

For uncertain nonlinear systems characterized by parameter uncertainties and unmodeled disturbances, an adaptive predefined‐time tracking control strategy is investigated in conjunction with disturbance observers. First, parameter uncertainties are addressed via predefined‐time adaptive laws, and a novel disturbance observer is devised to dynamically compensate for unmodeled disturbances. Subsequently, a predefined‐time controller employing predefined‐time filters is formulated based on the command‐filtered backstepping control framework. The proposed controller mitigates the “complexity explosion” issue and ensures continuous control signals during the control process. Theoretical analysis confirms that the proposed controller guarantees the tracking error converges to a small vicinity around zero within a predefined time, while the system's convergence time is arbitrarily predeterminable, irrespective of the system parameters. Ultimately, the validity of the developed controller is confirmed through two simulation examples.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
