Title:
POSITIONING CONTROL DEVICE AND POSITIONING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/176619
Kind Code:
A1
Abstract:
This positioning control device comprises a position command generation unit, a drive control unit, an evaluation unit, and a learning unit. The position command generation unit generates, on the basis of a position command parameter, a position command in which the forms of acceleration over an acceleration interval and a deceleration interval are independently defined. The drive control unit drives a motor such that a motor position indicating the position of the motor complies with the position command. The evaluation unit acquires, from an acceleration detection unit, an acceleration detection value indicating the acceleration of a controlled object, and calculates an evaluation value pertaining to the positioning performance of the controlled object on the basis of the motor position and the acceleration detection value after it has been concluded, on the basis of the motor position, that positioning control has been completed. The learning unit learns the relationship between the position command parameter and the evaluation value when positioning control has been performed multiple times and obtains a relational expression between the position command parameter and the evaluation value, while independently modifying each form of acceleration of the position command over the acceleration interval and the deceleration interval, which are determined according to the position command parameter.
