Development of An Upwind Linearized Harmonic Flow Solver For Turbomachinery Flows
Saygın, Aras; Baran, Özgür Uğraş; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2022-8-31)
Many modern turbomachines, especially turbofans and turbojets used in modern aircraft, contain many rotor-stator stages. The rotor stator rows of a typical modern aircraft engine are between 2 to 20 for fan-compressor part and between 2 to 7 for the turbine. Unsteady CFD analyses of rotor-stator systems are generally performed with minimal time steps due to the high relative speed of the rows. These CFD analyses should be performed for at least two complete rotations of the rows to achieve reasonable conver...
Development of a State Dependent Riccati Equation Based Tracking Flight Controller for an Unmanned Aircraft
Tekinalp, Ozan (2013-08-22)
A dual loop nonlinear State Dependent Riccati Equation (SDRE) control method is developed for the flight control of an unmanned aircraft. The outer loop addresses the attitude and altitude kinematics, while the inner loop handles the translational and rotational equations of motion. The control strategy utilizes a tracking control problem. The mismatch due to the SDC factorization of the inner loop is handled with a nonlinear compensator again derived from the tracking control formulation. The quadratic opt...
Development of an Intelligent Least Squares Based Linear Controller for Autonomous Helicopters
Kubali, Eser; Yavrucuk, İlkay (2016-06-10)
In this paper, a novel PID gain update law using linear least squares regression is introduced as an adaptive control method for autonomous helicopters. In addition, prediction analysis is conducted for error dynamics of the closed loop system using recursive linear least squares regression. Combining these two concepts with classical PID controller, an intelligent PID controller is obtained. A flight controller with three control loops is developed to demonstrate the capabilities of the controller. Finally...

An algorithm for visual topological localization and navigation is proposed. Landmark detection and tracking is performed in successive frames to determine angular changes between repetitive and salient features. This angular state is used to generate heading vector which will lead the robot to the target scene. This reactive navigation behavior is aided with localization and path planing algorithms to complete the SLAM capability. Our algorithm is tested in 2 different natural indoor environments. Results ...
