Title:
VIBRATION CONTROL DEVICE, MOTORIZED ACTUATOR DRIVE DEVICE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/081018
Kind Code:
A1
Abstract:
Provided is a vibration control device wherein appropriate measures are taken to prevent drive command signals from becoming excessive. Said vibration control device is provided with a reference wave generation means (3) for generating a reference wave (ejθ) from a fundamental frequency (f); a fundamental order number adaptation algorithm block (4a) which calculates fundamental order number adaptation filter factors (Re, Im) from the reference wave and a vibration detection signal (sg) detected from a position requiring vibration control, and generates a fundamental order number vibration control current command (I41) on the basis of the fundamental order number adaptation filter factors, with the result that a vibration having a phase opposite to that of a vibration from an engine (gn) that is a vibration generation source, is generated through a vibration excitation means (2) at the position requiring vibration control; an amplitude detection means (4b) for calculating a peak current value (A1') of the fundamental order number vibration control current command; and a fundamental order number current exceedance detection device (4c) for performing an operation wherein a predetermined fundamental order number current upper limit value (α1) is derived from the fundamental frequency, and wherein when the peak current value of the fundamental order number vibration control current command exceeds the fundamental order number current upper limit value, a fundamental order number current upper limit exceedance signal (S41) is generated and input into the fundamental order number adaptation algorithm block. While the fundamental order number current upper limit exceedance signal is being input into the fundamental order number adaptation algorithm block, the fundamental order number adaptation filter factors are made to be corrected within a predetermined range in such a way that the vibration control current command is restricted.
