AI-based Plant Control

摘要

Expectations for machine learning and artificial intelligence (AI) are growing globally and related investment has been increasing in a diverse range of businesses. Machine learning is used for autonomous car driving and robot control, and the use of its applications is rapidly increasing in factory automation (FA). On the other hand, practical process control techniques based on machine learning and AI have not yet been developed for process automation (PA) although data analysis using process data is becoming more common. PID control still remains the main technique and advanced control techniques by experts are used when complicated control is required. Not to simulate but to apply machine learning technology to actual equipment, we performed AI-based control of a three-tank-level control system, which is a popular educational kit for process control. This paper introduces the details of the experiment and the machine learning technology used to control this system.
