An implementation of iterative learning control in industrial production machines

This paper presents one implementation of an ILC (iterative learning control) algorithm in motion-focused production control systems. The implementation is an enhancement, but not a replacement of PID tuning. It is able to improve the system performance in terms of following error without re-tuning PID parameters when the operation conditions, such as mechanical device, load, and motion profile, change. The results are successfully demonstrated in Siemenspsila motion controller - Simotion, and utilized in industrial production lines. The proposed method possesses desirable implementation simplicity. According to the authorspsila knowledge, this paper is the first report of ILC implementation in the area of production machines.
