Title:
OPTIMAL INSTRUCTION CREATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/034163
Kind Code:
A1
Abstract:
An optimal instruction creation device for processing an instruction to be input to a servo controller so as to eliminate vibration of a control object having a vibration element and minimize the delay for the instruction. The optimal instruction creation device inputs an instruction, processes the instruction so that the control object can realize a desired operation, and outputs an optimal instruction value to the servo controller. The device includes an N-degree filter processing section (1) for performing an N-degree filter processing to the instruction and calculating the values of the differentiation of the first order to the N-1 order of the instruction which has been subjected to the filter processing and a four-operation section (2) for multiplying values of outputs from the N-degree filter processing section (1) by a gain and adding the products.
