Title:
PERIODIC DISTURBANCE AUTOMATIC SUPPRESSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/088054
Kind Code:
A1
Abstract:
When torque ripple is suppressed by using a periodic disturbance observer, the adjustment of a gain portion is determined by a sequence while monitoring an operation state, so that there is a number of adjustment parameters, and whether correction can be achieved or not depends on the skill of the adjustor or designer. A periodic disturbance observer is provided with a model correction means. The model correction means, on the assumption that a control command is zero and that the periodic disturbance is constant regardless of time, computes an identification model error by using temporal subtraction based on an output value from the periodic disturbance observer and a detected value from a plant. An identification model is corrected on the basis of the identification model error, and finally torque ripple suppression control is implemented on the basis of a highly accurate periodic disturbance estimated value.
