What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting ...

It is an open loop unstable system and it requires an efficient control scheme for a stable flight. This paper presents a discrete PID control scheme, which is able to move quadrotor to any point in 3 ...

Abstract: The control of underactuated constrained systems have proven to be a challenging task. This paper extends an intrinsic geometric PID controller developed for fully actuated mechanical ...
