Fault Tolerant Control of a quadrotor under actuator failures

Undergraduate Research, National Cheng Kung University (NCKU), Intelligent Embedded Control (IEC) Lab, Department of Aeronautics and Astronautics, 2018

The objective is to design a flight control algorithm for a quadrotor and study further how to recover control in the presence of single rotor loss.

Dual-spin Stabilization of a satellite

Graduate Course Project, University of Maryland, ENAE646-Advanced Dynamics, 2023

This goal of this project is to analyze the motion of a torque-free rigid body and determine its trajectory in the inertial frame.

Design of Longitudinal Control for Reduced-G Atmospheric Flight

Master Thesis Research, KAUST, RISC Lab, Department of Mechanical Engineering, 2023

This work proposed a triple-integral flight control framework for a zero-gravity flight using a proof-mass-tracking approach. A triple-integral control strategy is adopted to overcome unknown, quadratically increasing drag. Furthermore, to avoid the non-minimum phase characteristics of aircraft longitudinal dynamics (see below), the position deviation from the inertial reference is redefined such that the closed-loop system is minimum phase.

Adaptive Observer-Based Fault Detection and Fault-Tolerant Control of Quadrotors under Rotor Failure Conditions

Published in Applied Science, 2020

The objective is to design a flight control algorithm for a quadrotor and study further how to recover control in the presence of single rotor loss. The error transformation and reconfiguration techniques combined with sacrificing yaw control are applied to realize fault-tolerant control under actuator failures. The input saturation is not considered in our case.

Design of Longitudinal Control for Reduced-Gravity Atmospheric Flights

Published in AIAA SCITECH 2023, 2023

Parabolic flights are one way to simulate microgravity on Earth, which can be achieved by making aircraft follow specific flight trajectories. This work describes a kinematic and dynamic analysis of general partial gravity cases and develops a flight control framework for a zero-gravity flight using a proof-mass-tracking approach. A triple-integral control structure is adopted to overcome unknown, quadratically increasing drag. Furthermore, to avoid the non-minimum phase characteristics of aircraft longitudinal dynamics, the position deviation from the inertial reference is redefined such that the closed-loop system is minimum phase.
