摘要： A disturbance compensation control system which restricts periodic disturbance of a control object such as a motor includes a repetition control unit. The repetition control unit restricts the periodic disturbance to the control object. The repetition control unit is designed so as not to perform a repetition compensation control when the control object is initially started.

摘要： An embodiment of the present invention provides an object motion estimating device and the like, which solve a problem of assuming translational movement (that is, a spatial gradient is 0) of an optical flow and are suitable to estimation of an optical flow by an image analysis of captured images. The object motion estimating device performs the image analysis of the captured images of the object to estimate motion of the object. The object motion estimating device includes an image analyzing unit 15. The image analyzing unit 15 assumes time invariance of the optical flow while not assuming the translational movement, and the image analyzing unit 15 estimates the optical flow with intensity at each point of the captured images as measurement variable while simultaneously estimating a spatial gradient of the optical flow. The assumption about the translational movement of the optical flow is an assumption about the optical flow that is actually unknown. The proposed object motion estimating device can relax this assumption of the translational movement of the optical flow as much as possible.
