Title:
INPUT COMPENSATING AND CONTROLLING METHOD FOR VIBRATOR STAGE CONTROLLING SYSTEM
Document Type and Number:
Japanese Patent JPS5844508
Kind Code:
A
Abstract:
PURPOSE:To realize the accurate input compensation and control and to increase the regenerating accuracy of waveforms, by replacing the control system with a mathematics model and using the transmission properties obtained by the mathematics model. CONSTITUTION:The mathematics model transmission properties GA are used to perform the digital synthesization of the transmission properties to a control system. Thus the synthetic trnsmission properties G' are obtained and then smoothed. Here, A, B, C and D show the mathematics model transmission properties, the actual results transmission properties, the digital synthetic transmission properties C and the smoothing transmission properties respectively. The properties A are used in the case of ffH, where f, fL and fH show the frequency, low frequency and high frequency respectively. While the properties B are used with fL<=f<=fH. Thus the properties C are obtained. Then the properties D are obtained by applying a hamming filter to the properties C.
