hackflight
Hackflight is a simple, platform-independent, header-only C++ toolkit for building multirotor flight controllers. It is geared toward people like me who want to tinker with flight-control firmware, and use it to teach students about ideas like inertial measurement and PID tuning.

http://folk.ntnu.no/skoge/prost/proceedings/afcon03/Papers/050.pdf In this paper the Preitl and Precup equations for Symmetrical Optimum tuning are  further  refined  to  allow  explicit  specification  of  the  closed  loop  damping  factor. The resulting  tuned controller values are applied to position control of a dc servomotor. by Martin Braae  University cape town. http://folk.ntnu.no/skoge/prost/proceedings/afcon03/Papers/069.pdf

Arduino code and Five_axis_mill low cost alternative to parallel-port-based motion control for CNC milling. It will run on a vanilla Arduino (Duemillanove/Uno) as long as it sports an Atmega 328. The controller is written in highly optimized C utilizing every clever feature of the AVR-chips to achieve precise timing and asynchronous operation. It is able to maintain up to 30kHz of stable, jitter free control pulses Development of the PID controller by Stuart Bennett (IEEE Control Systems)
