Fuzzy Logic controller for an Iverted pendulum

[juani_c 66]

My project is an inverted pendulum. The pendulum is a kind of excuse; I wanted to make something to show a library I

Hi Juan,

I'm not familiar with fuzzy control, nor have I examined your code - so forgive me, but it looks like the pot has quite some friction and is able to hold the pendulum? Also, it seems to oscillate when you push it.

But it is an interesting experiment to get to know fuzzy control, thanks for sharing! I'll hope to find the time to set this up myself.

Hi Juan,

Fuzzy Logic is not anything complicated. It's just another Buzzword - in the fact it is the "analog processing" of data. Instead of digital "OFF" and "ON" is used analogue expression (scale: full "OFF" - a little "ON" - more "ON" - a lot of "ON" - full "ON"). Binary math is replaced with the counting numbers with floating decimal point. (Can also be used version, which counts with integer numbers - full "OFF" = 0x0000, full "ON" = 0xFFFF).

...and this is all. No magic.

For about 30 seconds of reading and 2 minutes of pondering time of your life, this Wikipedia article section alone with the nice image sums the concept up pretty well.

yes, that's due to a crappy potentiometer and a lightweight pendulum, in this kind of setups the device used to mesure the angle is usually some sort of optical encoder or something like that in order to avoid any kind of friction. Unfortunately I don't have such a device and I thought about making one but the potentiometer was a faster option.
