Backstepping Iterative Learning Control for Wiener System

Vibration suppression of an Euler–Bernoulli beam by backstepping iterative learning control

“…Faced with parametric uncertainties and input constraint, Tayebi and Chien [30] incorporates the adaptive control into the ILC methodology. A proportion–derivative (PD) type ILC is taken as a feed‐forward control to improve the convergence speed of the system with a backstepping feedback control [31]. Under the limitation of input saturation, a feedback‐based ILC is proposed to improve the performance of the tracking task [32].…”
