Neuromorphic Attitude Estimation and Control

IEEE Robotics and Automation Letters
The real-world application of small drones is mostly hampered by energy limitations. Neuromorphic computing promises extremely energy-efficient AI for autonomous flight but is still challenging to train and deploy on real robots. To reap the maximal benefits from neuromorphic computing, it is necessary to perform all autonomy functions end-to-end on a ...

Coaxial Helicopter Attitude Control System Design by Advanced Model Predictive Control under Disturbance

Aerospace
This paper proposes an advanced model predictive control (MPC) scheme for the attitude tracking of coaxial drones under wind disturbances. Unlike most existing MPC setups, this scheme embeds steady-input, steady-output, and steady-state conditions into ...

Benchmark: Quadrotor Attitude Control

EPiC Series in Computing, 2018
We present a case study of attitude control for a quadrotor and propose the application of reachability analysis to enhance the robustness of the control design.The controller is to be implemented and tested using an experimental nano-quadrotor platform, the \emph{CrazyFlie}.We intend to use measured data to improve the models employed in the ...
