proportional-integral (PI) controller in Vensim

In my last post, I discussed an attempt at designing a PID controller using the Kepler Scientific Workflow system. Here I report on a similar (yet successful) development of a proportional-integral (PI) controller in Vensim PLE. Vensim is a software package for describing and simulating dynamic models, particularly those involving feedback. I’ve often described it […]

attempted PID controller with Kepler

I wanted to check out the Kepler scientific workflow system (, and decided to build a PID controller model with it. Here I report on my results. The following schematic, taken from the Wikipedia entry, shows the basic configuration of a PID controller. PID stands for “proportional integral derivative”, reflecting the fact that the […]
