SERVO CONTROL APPARATUS CONTROL METHOD

摘要

When a current time target instruction value is received periodically from an upper node control apparatus, the instruction is performed without delay and modification of the instruction from the upper node control apparatus is flexibly accepted. In a servo control apparatus 2 for making an output of a control object 3 follow a target instruction received periodically from an upper node control apparatus 1, in each of the periods, a history of the target instruction is used to create a predicted target instruction up to the M-step future and by using the predicted target instruction, instruction following control is performed through prediction/forecast control or feedback gain switching control.
