Multi-Period Repetitive Control Design in a Time Delay Framework with Application to an Active Vibration Isolation System
Xiaoran Han, Sil Spanjer, Wouter B. J. Hakvoort
Multi-period Repetitive Control (MPRC) can lead to amplification at non-repetitive frequencies due to the multiplication of multi-period repetitive control in their closed-loop sen…
