Adaptive Control of Thrusters to Account for Deficiencies in Actuator Effectiveness and Model Uncertainties
… of freedom (DoF) to mitigate the effects of actuator deficiencies and system uncertainties. Additionally, the nature of the system being over-actuated allows for particular actuator degradation and failure. For stability and command tracking, a novel controller is designed and augmented with …

Sliding Mode Control with Chattering Reduction
… chattering phenomenon, which leads to potential actuator degradation, alterations to the desired response characteristics and, sometimes, instability during control implementation. The main objective of this thesis is to study Sliding Mode Control with chattering reduction. The Sliding Mode …

Adaptive Control Allocation for Unmanned Aerial Vehicles with Model Uncertainties
<p>Model uncertainties and effector degradation carry risks to weaken the performance of any aerial system and endanger operation during flight. To this end, over-actuated aerial systems are used in flight operations to take precautions for possible incidents, which may result in improper control …
