Title:
低温冷却装置アクティブ除振の適応位相制御
Document Type and Number:
Japanese Patent JP6395923
Kind Code:
B2
Abstract:
A method includes identifying a magnitude and phase angle of vibration forces resulting from a previous cancellation signal, where a first measured force vector is defined by this magnitude and phase angle. The method also includes identifying a magnitude and phase angle of a first cancellation force and transmitting a first AFF cancellation signal configured to generate the first cancellation force, where a first cancellation force vector is defined by this magnitude and phase angle. The method further includes identifying a magnitude and phase angle of vibration forces resulting from the first AFF cancellation signal, where a first resultant force vector is defined by this magnitude and phase angle. Moreover, the method includes determining whether a phase angle difference between the phase angles of the first resultant force vector and the first measured force vector is substantially equal to zero. If so, the method includes continuing to transmit the first AFF cancellation signal.
