(This is Modification #5 in a larger series on writing a solid PID algorithm) The Problem As nice as it is to have a PID controller, sometimes you don’t care what it has to say. Let’s say at some point … Continue reading →

(This is Modification #4 in a larger series on writing a solid PID algorithm) The Problem Reset windup is a trap that probably claims more beginners than any other. It occurs when the PID thinks it can do something that … Continue reading →

(This is Modification #3 in a larger series on writing a solid PID algorithm) The Problem The ability to change tuning parameters while the system is running is a must for any respectable PID algorithm. The Beginner’s PID acts a … Continue reading →

(This is Modification #2 in a larger series on writing a solid PID algorithm) The Problem This modification is going to tweak the derivative term a bit. The goal is to eliminate a phenomenon known as “Derivative Kick”. The image … Continue reading →

(This is Modification #1 in a larger series on writing a solid PID algorithm) The Problem The Beginner’s PID is designed to be called irregularly. This causes 2 issues: You don’t get consistent behavior from the PID, since sometimes it’s … Continue reading →

In conjunction with the release of the new Arduino PID Library I’ve decided to release this series of posts. The last library, while solid, didn’t really come with any code explanation. This time around the plan is to explain in … Continue reading →
