ADAPTIVE CONTROL DEVICE AND ADAPTIVE CONTROL METHOD, AS WELL AS CONTROL DEVICE AND CONTROL METHOD FOR INJECTION MOLDING MACHINE

摘要

Provided are an adaptive control device and adaptive control method, and a control device of an injection molding machine, which allow optimal adaptive control to be performed automatically and easily, while preventing a degradation of responsiveness. The adaptive control device is configured to perform feedback control in such a manner that an operation value (u) is output based on a command value (r) and a feedback value (y a ) which is a sum of a controlled value (y) output from a controlled target (2) and a compensation value (y f ) output from a parallel feed-forward compensator (4); wherein the parallel feed-forward compensator (4) includes: an identification section (6) which sequentially estimates a frequency response characteristic of the controlled target (2) and an adjustment section (7) which adjusts the compensation value (y f ) based on the estimated frequency response characteristic.
