Dynamic Modeling and LQR Control of a Single Coaxial Drone with 2DOF Thrust Vectoring Mechanism
Ali Jokar, Amin Talaeizadeh, Aria Alasty
Coaxial rotor drones have generated considerable interest because of energy efficiency and small size, but they are afflicted with inherent underactuation for roll and pitch contro…
Hybrid Neural Network and Conventional Controller Approach for Robust Control of Highly Unstable Systems: Application to Tilt-Rotor Control
Ali Kafili Gavgani, Amin Talaeizadeh, Aria Alasty +1
Multirotors are widely used in applications ranging from surveillance to precision agriculture, yet conventional designs remain limited by their under-actuation. Tilt-rotor configu…
Next-Generation Aerial Robots -- Omniorientational Strategies: Dynamic Modeling, Control, and Comparative Analysis
Ali Kafili Gavgani, Amin Talaeizadeh, Aria Alasty +2
Conventional multi-rotors are under-actuated systems, hindering them from independently controlling attitude from position. In this study, we present several distinct configuration…
Optimal time Quadcopter Descent Trajectories Avoiding the Vortex Ring and Autorotation States
Amin Talaeizadeh, Duarte Antunes, Hossein Nejat Pishkenari +1
It is wellknown that helicopters descending fast may enter the so called VRS, a region in the velocity space where the blade's lift differs significantly from regular regions. This…
