Nonlinear Controller Design for a Quadrotor with Inverted Pendulum

no code implementations4 Aug 2023 Xichen Shi, Yashwanth Kumar Nakka

The quadrotor is a $6$ degrees-of-freedom (DoF) system with underactuation.

Neural-Fly Enables Rapid Learning for Agile Flight in Strong Winds

1 code implementation13 May 2022 Michael O'Connell, Guanya Shi, Xichen Shi, Kamyar Azizzadenesheli, Anima Anandkumar, Yisong Yue, Soon-Jo Chung

Last, our control design extrapolates to unseen wind conditions, is shown to be effective for outdoor flights with only onboard sensors, and can transfer across drones with minimal performance degradation.

Neural-Swarm2: Planning and Control of Heterogeneous Multirotor Swarms using Learned Interactions

no code implementations10 Dec 2020 Guanya Shi, Wolfgang Hönig, Xichen Shi, Yisong Yue, Soon-Jo Chung

We present Neural-Swarm2, a learning-based method for motion planning and control that allows heterogeneous multirotors in a swarm to safely fly in close proximity.
