Abstract

This article addresses the challenge of achieving prescribed performance robust control for electro-hydraulic systems (EHSs) subject to input delays and output constraints. Firstly, a novel shift function that incorporates the information of input delays is introduced to construct a barrier function (BF). By stabilizing this BF, the output of the EHSs is guaranteed to reach the specified bounds within the prescribed time. Furthermore, by introducing the error transformation functions and the auxiliary function, we handle the tracking error constraints of EHSs in the presence of input delays without imposing any restrictions on the initial relationships between error variables and predefined boundaries. Finally, the proposed controller design does not rely on any specific knowledge of EHSs and avoids the use of approximation or adaptive techniques. Based on Lyapunov stability theory and proof by contradiction, we prove that the closed-loop system is stable. Experimental results demonstrate the effectiveness of the proposed approach.

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.
