Industrial AI operates in the physical world. A compressor has a real operating envelope. A distillation column has hydraulic and thermodynamic limits. A reactor has temperature and pressure ...

Measurements such as temperature, pressure, flow and torque can help determine what is happening in a reactor, but they don't necessarily characterize the macromolecular properties that determine the ...

Successful manufacturing is inextricably linked to process control. If processes are not controlled, the eventual output may not fall within the required parameters. Using baking as an example, when ...

The process control group in refineries, chemical plants, power plants, and other industrial process facilities is responsible for applying and maintaining automation and other operational ...

The two basic modes of process control are sequential control, or On/Off action, and continuous control action. This chapter deals with process control, discussing both sequential and continuous ...

I recently surveyed the on-site development of the control system for a large concentrated solar power station. This “first of a kind” facility offered many control challenges, such as balancing heat ...

One of the key ideas in lean manufacturing is that defects should be detected as early as possible. Efforts to control manufacturing processes so that issues can be detected before defects occur ...

Process manufacturers have been using advanced process control (APC) and online optimization technologies for several decades. Advances are being made on the business front, increasing manufacturers’ ...

Overlay control based on DI metrology of optical targets has been the primary basis for run-to-run process control for many years. In previous work we described a scenario where optical overlay ...
