I'd like to announce two control packages that I hope are useful to the community. First is the basic pid package for the PID controllers that engineers love so much:

One of the nice features of the pid package is low-pass filtering on the data and the derivative calculation, which reduces noise and erratic control effort.

For more complicated control problems, there is the lyap_control package:

It can handle simple control problems too, but it really excels at high-order, coupled, over-actuated, or otherwise complicated systems. It can do some cool things like controlling seven motors simultaneously with minimal tuning.

Cheers,

Andy
