Fuzzy Logic

Fuzzy Logic is an unconventional control scheme used for systems that are hard to model but about which some operational knowledge is available.  Rules of thumb and even intuition can be coded into a fuzzy rule base and used to come up with a control algorithm for a system that defies analysis.  Fuzzy control algorithms have been used encode control information from everything from concrete kilns to parallel parking problems.

I wrote a fuzzy controller to be used on a Large Scale Manipulator.  The fuzzy algorithm is written in C++.  It allows for a flexible resolution of rule gradations to be specified.

I also worked on the new fuzzy controller that is part of the Delta V control system.
