AI Control Learning Service

Please refer to the catalog for an explanation of our AI control learning service using YOKOGAWA's Reinforcement Learning AI.

e-RT3 Plus Industrial AI Platform

Yokogawa's reinforcement learning AI, which succeeded in autonomous control of plants using AI for the first time in the world^*, can now be implemented with the e-RT3 Plus.

The industrial AI platform and Yokogawa's reinforcement learning AI are now available as a package. We provide an environment where customers can work independently on their own AI control. The AI control learning tool is provided in a cloud environment, so you can always use the latest AI control learning tool. It is possible to reduce the need for new infrastructure development and system construction.

^* Based on Yokogawa Electric survey conducted in February 2022 regarding AI that directly changes the manipulative variable in the chemical plant.

Features of Yokogawa's reinforcement learning AI

With PID control which widely used in control, high-precision control can be achieved when conditions are straightforward, but becomes difficult when there is a large disturbance in the control state or when there is a long dead time. In many cases, adjustments must be made based on intuition and experience. AI easily utilizes empirical knowledge through learning, and can frequently derive answers even if a theory has not been established.

Yokogawa's reinforcement learning AI “Factorial Kernel Dynamic Policy Programming” (FKDPP)^* is very practical because it requires fewer trials than general reinforcement learning.

* This is a reinforcement learning AI algorithm jointly developed by Yokogawa Electric and Nara Institute of Science and Technology (NAIST), and was the first in the world to be recognized by IEEE International Conference on Reinforcement Learning.

Expected benefits of AI control

1. Securing the Future Workforce and Shifting to Automation
   By automating process^*1, which required human coordination, with AI, we will solve the labor shortage at the site.
   ^*1: A process that relies on the intuition and experience of skilled engineers / A process that requires human adjustment every time a disturbance occurs
2. Contribute to improving control
   It is possible to control with suppression of overshoot. It is possible to reduce the load on the equipment by improving control.
3. Both productivity and energy saving (Contribute to sustainability)
   By control that shorten the settling time, it is possible to secure productivity (quality, yield, etc.) while reducing wasted energy.

For new purchases, we offer the F3RP70-2L/L09 OS-Free CPU module with AI control license.

^*1:AI control learning does not guarantee the generation of the best control model.
The performance of a control model varies depending on the characteristics of the equipment and the quality of the data provided.

To use the AI control learning tool, please apply^*2 at our dedicated website. After applying, a user account will be created in the cloud environment and you can begin using the tool. The tool is an annual subscription. To create an AI control model, you need to prepare either an actual machine or a simulator. If employing a simulator, you can create one using the simulator^*3 function included with the AI control learning service.

^*2: The product serial number shipped from the factory is required to apply. Please contact us for the sales area, as it is necessary to confirm the use of the cloud service.
^*3: The simulator corresponds to single input and single output per the system identification method. If the controlled equipment has multiple inputs and outputs, it is necessary to prepare a separate simulator.

Two Control modes

Application

In combination with proven industrial controllers, our AI control can be used in a wide range of applications, including plant and machine control.

• Supports control periods from 0.01 seconds, and equipment control that requires high speed
• Multiple control loops can be processed in a single controller
• Hybrid control that takes advantage of the features of P ID and other conventional control methods

Main markets

Point!

• While ensuring quality, overshoot (which is difficult to adjust) is suppressed while reducing dead time
• Contributes to energy saving by improving efficiency
• Improvement of transient characteristics prevents unnecessary load on the heater and contributes to extending the life of the equipment
