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...
Development of an octree based grid coarsening and multigrid flow solution
Mahmutyazıcıoğlu, Emel; Aksel, Mehmet Haluk; Tuncer, İsmail Hakkı; Department of Mechanical Engineering (2010)
The multigrid technique is one of the most effective techniques to achieve the reduction of the CPU cost for flow solvers. The multigrid strategy uses the multilevel grids which are the coarsening subsets of fine grid. An explicit solver rapidly reduces the high frequency errors on the computational grids. Since high frequency errors on coarse grids correspond to low frequency errors on fine grids, cycling through the coarse grid levels rapidly reduces the errors ranging from high-to-low frequency. The aim ...

Development of a multi-scenario simulation model for spare parts inventory optimization in mining operations
Şenses, Sena; Gölbaşı, Onur; Department of Mining Engineering (2021-8)
The growing market competition compels many industries to change their operational structures at strategic and operational levels dramatically. It has been recognized that inventory management requires continuous monitoring and improvement and it is vital for businesses to ensure smooth operations by avoiding production loss and reducing the overall cost of inventory. For various production companies operating in different industries, inventory is considered as one of the most expensive assets. Among differ...
Development of a discrete adjoint-based aerodynamic shape optimization tool for natural laminar flows
Kaya, Halil; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2020)
An adjoint-based aerodynamic shape optimization framework for natural laminar flows is developed. A Reynolds-Averaged Navier-Stokes flow solver with the Spalart-Allmaras turbulence model is coupled with the recently developed Bas-Cakmakcioglu transition model in order to predict laminar to turbulent transition onset. In the gradient-based optimization process, the sensitivity derivatives required by the optimization algorithm is obtained by the discrete adjoint method, which is developed for the in-house fl...
