Title:
ADAPTIVE CONTROL DEVICE AND ADAPTIVE CONTROL METHOD, AS WELL AS CONTROL DEVICE AND CONTROL METHOD FOR INJECTION MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2013/031082
Kind Code:
A1
Abstract:
Provided are an adaptive control device and adaptive control method, as well as a control device and control method for an injection molding machine, capable of preventing a loss in responsiveness while optimal adaptive control is carried out in an automatic and simple manner. An adaptive control device for carrying out feedback control so that an operation value (u) is outputted on the basis of a command value (r) and a feedback value (ya) in which a compensation value (yf) outputted from a parallel feed-forward compensator (4) is added to a control value (y) outputted from a control target (2), wherein the parallel feed-forward compensator (4) is provided with an identification mechanism (6) for sequentially estimating frequency response characteristics of the control target (2), and an adjustment mechanism (7) for adjusting the compensation value (yf) on the basis of the frequency response characteristics.
