Design of a trajectory contour controller for a dual‐axis precision motion stage based on improved iterative learning

IET Control Theory &Applications, Volume 17, Issue 17, Page 2280-2291, November 2023., 2023
Here, the Contour Error(CE) in the precision motion control of a dual‐axis planar mechanism is addressed. The Precompensation Cross‐Coupling Iterative Learning Control with Variable Forgetting Factor (pre‐CCILC+VFF‐VGILC) control strategy significantly improve the “single‐axis Tracking Error (TE) and dual‐axis CE” under repeated trajectories.
