Title:
PERIODIC EXTERNAL DISTURBANCE SUPPRESSION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/115623
Kind Code:
A1
Abstract:
A periodic external disturbance suppression device, wherein corrections can be made while an inverse model of the transmission characteristics of a real system is sequentially estimated, and a stable control system is produced even when the change of state of the real system is considerable. The periodic external disturbance to be suppressed is outputted as a periodic external disturbance detection value (ISdn, ISqn) of a direct current component, and the difference between a signal obtained by multiplying the periodic external disturbance detection value (ISdn, ISqn) with the aid of an integrator using the reciprocal (Qn) of the transmission characteristics, and a signal obtained by adding only a detection delay to a harmonic suppression command value (I*dn, I*qn) is determined to estimate the periodic external disturbance (dI^dn, dI^qn). The variation between the periodic external disturbance estimated value (dI^dn, dI^qn) and the periodic external disturbance command value (dI*dn, dI*qn) is acquired to calculate the harmonic suppression command value (I*dn, I*qn). The reciprocal (Qn) of the transmission characteristics is corrected by a learning control unit (29) in accordance with a value obtained by dividing the difference between single samples of the harmonic suppression command value (I*dn, I*qn) by the difference between single samples of the harmonic direct current detection value.
