Stability and optimal control of a fully-actuated tilt-rotor with delayed feedback
摘要
This paper addresses the control problem of a tilting quadrotor-an unmanned aerial vehicle (UAV) with a reconfigurable structure that enhances flight performance and enables multi-tasking capabilities. To tackle the challenges posed by time-delayed dynamics in altitude and servomotor responses, this work proposes a set of computationally efficient yet robust Proportional-Derivative (PD) control algorithms. These algorithms effectively mitigate such delays. The control design leverages a linearized mathematical model of the longitudinal motion within the x-z plane, derived using the Newton-Euler formalism. To ensure closed-loop stability, the analysis employs a geometric approach to explore the parameter space of the controller gains and delineates stability regions. The design further enforces
