Online education benefits for process instrumentation, control

In-person training for process instrumentation and control (PIC) provides valuable training on-site for engineers, but online education can save time and money for everyone involved while giving engineers a base of knowledge they can build from.

Figure: Rate-predictive control (RPC) uses a pre-set move rate, and tapers the move based on the PV’s predicted (apparent or already manifest) value. The U.S. Patent and Trademark Office (USPTO) has hundreds of patents for process control; as of this writing, RPC is the only one with the claim of being inherently adaptive.
