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…
Design of Adaptive PID Controller Based On Asynchronous Advantage Actor Critic Learning Method for QuadCopter Control
Ali Jokar, Aria Alasty
Quadcopters offer great utility in many applications, but their nonlinear nature and disturbance sensitivity present great control challenges. Basic PID controllers are generally n…
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…
Self-Tuning PID Control via a Hybrid Actor-Critic-Based Neural Structure for Quadcopter Control
Iman Sharifi, Aria Alasty
Proportional-Integrator-Derivative (PID) controller is used in a wide range of industrial and experimental processes. There are a couple of offline methods for tuning PID gains. Ho…
Design and Implementation of a Controller for Hexaglide CNC Machine
Kaveh Safavigerdini, Aria Alasty, Mohammad Reza Movahhedy
The objective of this research is to develop an advanced controller for CNC machines equipped with Hexaglide parallel mechanisms. While traditional CNC machines employ mechanisms w…
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…
Boundary Vibration Control of Strain Gradient Timoshenko Micro-Cantilevers Using Piezoelectric Actuators
Amin Mehrvarz, Hasan Salarieh, Aria Alasty +1
In this paper the problem of boundary control of vibration in a clamped-free strain gradient Timoshenko micro-cantilever is studied. For getting systems closer to reality, the forc…
Admissibility and Exact Observability of Observation Operators for Micro-Beam Model: Time and Frequency Domain Approaches
Mohammad Sajjad Edalatzadeh, Aria Alasty, Ramin Vatankhah
This study focuses on the exact observability of a non-classical Euler-Bernoulli micro-beam equation. This non-classical model was derived based on the strain gradient elasticity t…
