RESONANCE SUPPRESSION CONTROL CIRCUIT AND TESTING SYSTEM EMPLOYING SAME, AND METHOD OF DESIGNING RESONANCE SUPPRESSION CONTROL CIRCUIT

WIPO Patent Application WO/2017/221876

A1

The objective of the present invention is to provide a resonance suppression control circuit capable of providing operation that is stable with respect to variations with a low order mode of vibration while at the same time suppressing spill-over due to a high order mode of vibration. This resonance suppression control circuit controls a physical system having two or more modes of vibration, and suppresses resonance in a low order mode of vibration that is the lowest order mode of vibration from among the plurality of modes of vibration. The resonance suppression control circuit is provided with a controller that is designed by means of a µ design method, using a generalized plant P1 provided with a nominal model N1, and a structured perturbation to the generalized plant. The nominal model N1 is represented by the product of a low order vibration mode transfer function M1 (s) having the low order mode of vibration to be suppressed, and a high order vibration mode transfer function Hx (s) having a high order mode of vibration. The structured perturbation includes a first parameter perturbation term δ1 which imparts a multiplicative error to a spring constant K1 included in the vibration mode transfer function M1 (s) to be suppressed.
