Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/217445
Kind Code:
A1
Abstract:
Provided is a control device having a neural network with the ability to perform learning without being affected by dead time even in a dead time system and improve a transient response to a command input. This control device (1) comprises: a feedback controller (10) which controls a control target including a dead time element; a reference model unit (20) which includes a dead time element and outputs a desired response waveform for an input; and a learning controller (30) which produces an output which is added to the output of the feedback controller and inputted to the control target and which performs learning such that the error between the output of the reference model unit and the output of the control target caused by a change in the output from the learning controller is either minimized or less than or equal to a predetermined threshold value.
