Striatech's switched reluctance (SR) motor and dedicated control combination is designed for industrial applications such as large conveyors for steady operation.
Top 5 Control Engineering articles, December 9 to January 8: PID loop tuning advice, control engineers and management, System Integrators of the Year, more
Articles about learning PID loop turning from an expert, 7 things control engineers should know about management, the 2015 System Integrators of the Year, support-focused enterprise controls, and PLC and DCS programming were Control Engineering’s five most clicked articles from December 9 to January 8.
The most important constraint in a real-time system is that the time it takes to process an input and produce an output must be well known.
Harting's Han-Eco Outdoor and Han-Yellock connectors are designed to resist harsh environmental conditions while the Han-M has UV resistant seals and the Han HPR is used for demanding environments and wet areas.
The OBR40 optical bypass relay by Belden is designed for harsh environments and both ring and bus topologies as well as an IP30 protection rating.
Sometimes we need to think about an individual control loop. Other times we need to consider the larger control system. You should be able to do either when appropriate.
When regulatory control can’t do the job, and you can’t find an off-the-shelf APC package, your only option may be to build your own. It’s not easy, but it can be done and good ones can make a world of difference.
Concepts of APC can be implemented a little bit at a time but still make big steps toward getting your process running better.
Don’t think it’s lazy—reusing effective control system strategy and programming can help you identify problems.
These technologies continue to evolve, making differences harder to distinguish. Here are some thoughts on what does what, and how to choose between a PLC and a PAC for your next application.
