Title

OPTIMAL CONTROL OF VORTEX SHEDDING AROUND SQUARE CYLINDER VIA REDUCED ORDER MODEL

Pages

  49-62

Abstract

 In this paper, OPTIMAL CONTROL of VORTEX SHEDDING behind square cylinder in laminar flow regime (Re=200) has been investigated. When Navier-Stokes equations are used as state equations, the discretization of the optimality system leads to large scale optimization problems that represent a tremendous computational task. In order to reduce the number of state variables during the optimization process, a Reduced-Order Model (ROM) based on POD MODES is derived to be used as state equations. Then, these equations are modified by introducing a Control Function to ROM in order to gain equations which are suitable for OPTIMAL CONTROL. Optimal trajectory for control input has been found by employment of Quasi-linearization which is one of the numerical methods for solving OPTIMAL CONTROL.
