Mitsubishi Electric and National Institute of Advanced Industrial Science and Technology Collaboration
Mitsubishi Electric Corporation and the National Institute of Advanced Industrial Science and Technology (AIST) announced that they have developed an artificial-intelligence (AI) technology that can reduce time for setting up factory-automation (FA) equipment. The new technology, which combines AIST’s AI technologies and Mitsubishi Electric’s FA technologies for highly effective application in the FA field, will be implemented in Mitsubishi Electric’s Maisart®1 products for greatly increased factory productivity.
1 Mitsubishi Electric’s AI creates the State-of-the-ART in technology
The time for setting up FA equipment and systems prior to production, such as tuning or programming, is increasing in line with the growing demand for small-lot production. In addition, the supply of experts capable of performing such procedures is becoming insufficient. In response, Mitsubishi Electric collaborated to develop an AI technology that reduces the time for setting-up FA equipment and systems.
1) Servo system 2 positioning parameters tuned automatically in one day
- Mitsubishi Electric’s drive-control expertise is combined with AIST’s Bayesian optimization3 application technology to enable positioning parameters to be tuned automatically in one day compared to one week for manual tuning by experts.
- High-speed positioning control cuts positioning time up by to 20 percent using as many as 720 parameters in eight categories, which even experts would have difficulty adjusting.
2 Drives and controls various industrial machines at high speed and with high accuracy
