Experimental Study on Active Vibration Control of a Piezo-Beam Structure with Finite Series Based Adaptive Controller Gezer, R. Berk; Alan, A. Burkay; Kutay, Ali Türker; Şahin, Melin (2024-01-01) This study presents an experimental investigation of an active vibration control system implemented on a piezo-beam structure consisting of a cantilever beam with lead zirconium titanate (PZT) patches positioned at the roo...
Full envelope nonlinear flight controller design for a novel electric VTOL (eVTOL) air taxi Suiçmez, E.C.; Kutay, Ali Türker (2023-10-01) On-demand urban air transportation gains popularity in recent years with the introduction of the electric VTOL (eVTOL) aircraft concept. There is an emerging interest in short/medium range eVTOL air taxi considering the cr...
Optimization of reward shaping function based on genetic algorithm applied to a cross validated deep deterministic policy gradient in a powered landing guidance problem Nugroho, Larasmoyo; Andiarti, Rika; Akmeliawati, Rini; Kutay, Ali Türker; Larasati, Diva Kartika; Wijaya, Sastra Kusuma (2023-04-01) One major capability of a Deep Reinforcement Learning (DRL) agent to control a specific vehicle in an environment without any prior knowledge is decision-making based on a well-designed reward shaping function. An importan...
Comparison of Deep Reinforcement Learning-Based Guidance Strategies under Non-Ideal Conditions Aydinli, Sevket Utku; Kutay, Ali Türker (2023-01-01) This paper proposes three reinforcement learningbased guidance strategies to solve the problem of quadcopter guidance under non-ideal conditions such as target movement, measurement delay and system delay. The engagement s...
Single channel digital controller design for a high spinning rate rolling airframe missile Suicmez, E. C.; Kutay, Ali Türker (2022-04-01) Spinning/Rolling Airframe Missiles (RAM) mostly use an analog (ON-OFF type) control approach that deflects control surfaces (fins) at minimum and maximum positions continuously, and control is achieved by applying phase sh...
A Modification to Adaptive Control with Time-varying Learning Rate for Improved Transient Performance Yayla, Metehan; Kutay, Ali Türker (2022-01-01) © 2022, American Institute of Aeronautics and Astronautics Inc. All rights reserved.In this study, we propose a new adaptive weight update law using frequency-limited estimation of the matched uncertainty. Many adaptive pa...
Energy-based adaptive flight controller for improved coordinated longitudinal control Kutlu, Aykut; Yayla, Metehan; Kutay, Ali Türker (2021-01-01) In this study, we propose an adaptive longitudinal flight controller in the sequential loop closure framework using the energy principles. In contrary to traditional SISO classical control theory based flight control archi...
Identification of Physical Helicopter Models Using Subspace Identification Avcioglu, Sevil; Kutay, Ali Türker; Leblebicioğlu, Mehmet Kemal (2020-04-01) Subspace identification is a powerful tool due to its well-understood techniques based on linear algebra (orthogonal projections and intersections of subspaces) and numerical methods like singular value decomposition. Howe...
