Estimating the term…
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 is output based on a command value and a feedback value which is a sum of a controlled value output from a controlled target and a compensation value output from a parallel feed-forward compensator; wherein the parallel feed-forward compensator includes: an identification section which sequentially estimates a frequency response characteristic of the controlled target and an adjustment section which adjusts the compensation value based on the estimated frequency response characteristic.
An adaptive control device comprising:
A control device of an injection molding machine which includes a pressure controller which outputs a pressure operation value to a motor for adjusting a pressure in a hydraulic cylinder of the injection molding machine;
An adaptive control method using a control system constructed by adding a parallel feed-forward compensator to a controlled target, comprising the steps of:
A method of controlling an injection molding machine which uses a control system constructed by adding a parallel feed-forward compensator to a pressure in a hydraulic cylinder of the injection molding machine, the method comprising the steps of:
