Title:
MULTIDEGREE-OF-FREEDOM VIBRATION EXCITER AND ITS CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3811639
Kind Code:
B
Abstract:

PROBLEM TO BE SOLVED: To provide a control device which carries out excitation highly accurately even when an interference exists between state quantities and a property of an object to be excited is nonlinear.
SOLUTION: The transfer function matrix G(k) of an object 1 to be controlled is sequentially identified in real time by an identification means 4. An adaptive filter 3 corrects a command vector U(k) to the object 1 to be controlled in real time so that the response of the object to be controlled coincides with a target on the basis of the identification result. In the adaptive filter, correction calculation is carried out according to a control circuit in which each element transfer function of a sequentially identified transfer function matrix G(k) and its inverse transfer function are connected in combination of series connection, parallel connection and feedback connection.
