Abstract The potential application of process monitoring and control in various industries is infinite and the impact is major. With computer-aided design and manufacturing, the process and tools can be managed beyond the reach of human hands. In the current environment, where computing power is increasing on an exponential scale and application software has been developing like blossoming spring flowers, material manufacturers can easily capitalize on these advantages. Conversely, major research is still needed in the in-situ sensing of material properties, the processing environment during fabrication processes, and adaptive control schemes to feed these parameters back to the process controllers.

Abstract An expert system is a computer software technology developed from artificial intelligence research. It may be used for intelligent manufacturing process control and, when properly designed, has the capability to imitate human behavior. An expert system’s value is to assist a human in executing realtime process control decisions in a complex system. This article provides an introduction to the concepts of intelligent process control and includes a process control scenario applying an expert system as well as statistical and optimization technologies. A simple guide of how to get started and a description of expert system tools are also presented.

Abstract Intelligent control is an attempt to specify the function of a controller in ways which mimic the decision-making capabilities of humans. Traditionally, issues relating to the emulation of human-like capabilities have fallen in the domain of artificial intelligence. Intelligent processing is a specific form of intelligent control in which the system to be controlled is a process rather than the more conventional mechanical or electrical system. The National Institute of Standards and Technology’s program on intelligent processing of metal powders is a multi-disciplinary research initiative investigating the application of intelligent control technologies to improve the state of the art of metal powder manufacturing. This paper reviews the design of the institute’s supersonic inert-gas metal-atomizer control system.

Abstract Induction-coupled plasma deposition (ICPD) is currently a laboratory process relying on operator expertise rather than automated control. Intelligent process control for the ICPD process, which consists of integration of processing knowledge, process models, process sensors and control technology, offers the opportunity to provide closed-loop control as well as intelligent supervisory control to accelerate process development and bring the ICPD process to full-scale production. Intelligent process control for ICPD offers benefits such as higher material quality, control of the matrix micro-structure, cost reduction, higher process yield, and shorter development and production cycle times.
