Advanced system control techniques

I am interested in doing some hobby projects using advanced control systems. Has anyone had any luck designing control systems using neural networks or fuzzy logic on PICs? I have done this purely in a software/hardware-in-the-loop simulations using MATLAB while in college. Has anyone has success using this type of AI in these controllers? Thanks for your input!

Greetings,

I've played around with fuzzy logic on a servo motor control project using a PIC18F4585 and a potentiometer for lever arm position feedback. The logic I implemented used discrete steps and integer values instead of combining multiple rules into a continuous function. In the end, I wound up using PID with a few elements of fuzzy logic for special cases of motion. The fuzzy logic would have worked, but the requirements of the project and the time available for tuning was a little more than the PID solution.

Cheers,
