test driving the Kepler scientific workflow system

The Kepler scientific workflow system enables scientists and engineers to specify their software pipelines as chains of visual dependencies. Each node in a pipeline runs a specific task, and it does not matter what programming language the task is written in since Kepler only manages the inputs and outputs of each step. Here I describe […]

attempted PID controller with Kepler

I wanted to check out the Kepler scientific workflow system (https://kepler-project.org/), and decided to build a PID controller model with it. Here I report on my results. The following schematic, taken from the Wikipedia entry http://en.wikipedia.org/wiki/PID_controller, shows the basic configuration of a PID controller. PID stands for “proportional integral derivative”, reflecting the fact that the […]
