When is PID Not the Answer?
Social media group member posits the question: How come PID is the answer to so many applications? Is it because advanced control is rarely needed or that control engineers are not pushing the envelope?

Цитата:
PID has long been one of the more popular topics covered at Control Engineering, and for good reason—our subscribers see it as an integral component of their work. The popularity of the topic among control engineers worldwide does not appear to be waning either. Looking back over the past two years, loop tuning and PID-related articles are consistently among the most popular articles visited on the Control Engineering Website.
So when Parasar Kodati, application support engineer at the MathWorks, posted this question on the Automation & Control Engineering LinkedIn site: “When PID is not the answer: What is Advanced Control good for?” a high level of response was assured.
Kodati noted that, while a graduate student, he was “amazed by the subject of control and couldn’t wait to see the applications of the theory applied in industry.” Three years after graduation, however, he began to wonder why PID seemed to be the answer for so many applications.
