Backstepping Control of an Electro-Hydraulic Actuator using Kalman Filter
Abstract
This paper presents the development of a Kalman filter-based controller for an electro-hydraulic actuator (EHA) system in the face of the disturbance white noise and unmeasurable system states. First, the continuous nonlinear EHA system is converted to a discrete system. Second, the discrete system is linearized to facilitate the filter design. Next, a Kalman filter (KF) is constructed to simultaneously estimate the unmeasurable system state and reduce the noisy sensor measurements. Then, backstepping control technique using KF approach is synthesized to not only obtain accuracy tracking control but also eliminate the disturbance white noise under unmeasurable system states. Finally, simulation evaluations and comparison studies are investigated to validate the feasibility of the presented method.

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.
