Figure: Rate-predictive control (RPC) is inherently adaptive (think naturally self-tuning) to changes in process gain. In the top graph, process gain is 1.0, while in the bottom graph, process gain is 2.0. Control performance remains “perfect,” with no change to RPC tuning parameters. Courtesy: APC Performance LLC

The top 5 most read articles online, from September 30 to October 6 for Control Engineering covered RPC and model-based control, water/wastewater applications, OOIP, advanced process control, and prolonging power plant life. Links to each article below.

1. Advantages of RPC and limits of model-based control

Part 3: Rate-predictive control, an alternative algorithm to proportional-integral-derivative (PID) and model-based control, can provide single-loop control. See three RPC advantages and two model-based control limitations.

2. Water, wastewater industry is going digital and getting smarter

The water and wastewater industry is improving digitalization and automation with smarter sensors designed to make operations safer.

3. OOIP Part 3: interfaces and methods

Interfaces and methods used in object-oriented industrial programming (OOIP) help deliver productivity of object-oriented programming (OOP) without the complexity. Because plants and equipment are assembled from objects, it’s logical that their control programming should be, too.

4. Five advanced process control, data analytics connections

Are there connections between advanced process control (APC) and data analytics? Recent developments in the field of information technology (IT) and its use in the manufacturing world provide insights.

5. Prolonging power plant life through artificial intelligence

A West Virginia University chemical engineer is tapping into artificial intelligence (AI) to prolong the lives of power plant boilers.

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, Sept. 30 to Oct. 6, for articles published within the last two months.
