Last year, some controversy broke out in the process automation and control community about the use of Lambda tuning for proportional-integral-derivative (PID)-based control. In a post, Lambda Tuning-Yeah or Neah?, we offered a differing view to a Control magazine article, The Case Against Lambda Tuning. Emerson’s Mark Coughran has written an excellent whitepaper that is […]
