Extended‐state‐observer‐based adaptive robust control of a single‐axis hydraulic shaking table
IET Control Theory &Applications, Volume 18, Issue 4, Page 442-453, March 2024.This paper presents a novel approach to the acceleration trajectory control problem of single‐axis hydraulic shaking table systems from a non‐linear perspective. This strategy employs a controller combined with an extended state observer and adaptive control, offering a design that more closely reflects real‐world scenarios and requires less parameter ...
