Differential_drive PID controller bug?

Hi everyone,

I am having issues tuning the PID parameters for the differential drive package. I see on the external site there is a mention of a few bugs in the PID controller. The controller tends to work correctly but sometimes reacts very slowly after a few seconds. My motors often stall and the controller takes a long time to increase and overcome the friction of the wheels. Ive tried to increase the integral gain but it still takes too long.

I am not a controller wiz so cant really debug the program. Has anybody used the package and find any bugs?

Any help will be greatly appreciated.

Also, does anybody know what the rolling_points parameter means? should it be tuned or adjusted?

Any help will be greatly appreciated.
