I am retiring from Emerson later this month. It has been a real pleasure working at Emerson and to share with subscribers of this blog some of my work on control and simulation. I greatly appreciate the many opportunities I had to help shape the control capability in DeltaV, to lead the function block application work in ISP and FF, contribute to ISA and IEC standards committees, to lead the development of DeltaV Advanced Control products. Also, over the last eight year I have enjoyed working in the applied research team on the development of PIDPlus for wireless control, continuous and batch analytics, high speed control and to co-author the Foundation book series. Many thanks to the people I have worked with over the last 42 years. In this blog posting I want to share with you some memories from the past. I hope you enjoy this video.
