Title:
LEARNING CONTROL METHOD
Document Type and Number:
Japanese Patent JP3031499
Kind Code:
B2
Abstract:
PURPOSE: To improve the follow-up precision by making a learning starting spot into not the starting spot of a target command but the spot where deviation is zero or the spot near it.
CONSTITUTION: In a learning control system to repeat the trial so as to follow up the controlled to a target command to repeat the same pattern, a deviation deciding part is provided, and it decides whether or not the difference between the position of a motor and the target position command becomes zero. When the difference does not become zero, it is decided that the spot near the zero is zero. When the decision is performed, a learning starting command is generated to a learning controller and the learning is started. Even when the special deviation deciding part is not provided, realization is possible by changing the software in the learning controller.
