“…where 𝑃 (𝑠) and 𝑃 (𝑠) represent the transfer functions (TF) from the control input 𝑒 to the motor side and table side position, 𝑦 and 𝑦 , respectively. Then 𝑃 (𝑠) defined in (12) is the TF from the motor side position to the table side position. In addition, π‘ž = π‘š π‘š , π‘ž = (π‘š + π‘š )𝑐 + π‘š 𝑐 + π‘š 𝑐 , π‘ž = (π‘š + π‘š )π‘˜ + 𝑐 𝑐 + (𝑐 + 𝑐 )𝑐 , and π‘ž = (𝑐 + 𝑐 )π‘˜ .…”

“…Conversely, a feedforward control signal can be designed to preemptively target future reference commands and disturbances, utilizing an understanding of the system’s dynamics and the information at hand. Techniques like notch filtering [ 12 ] and input shaping [ 13 ] are employed to modify the spectral energy around the resonance frequency in trajectory commands, aiming to reduce vibrations induced by the trajectory. Yet, these approaches may introduce additional delays and can distort trajectory commands, which can compromise the accuracy of contour tracking in multi-axis motion.…”
