Optimal Control of Open-Channel Flow Using Adjoint Sensitivity Analysis
An optimal flow control methodology based on adjoint sensitivity analysis for controlling nonlinear open channel flows with complex geometries is presented. The adjoint equations, derived from the nonlinear Saint-Venant equations, are generally capable of evaluating the time-dependent sensitivities with respect to a variety of control variables under complex flow conditions and cross-section sh...
متن کاملNumerical Tools for Unsteady Viscous Flow Control
Abstract: This paper reports about progress in the development of numerical tools for adaptive aerodynamic configuration design. We try to illustrate the use of new software components allowing for the parameterized modelling of boundary conditions and the simulation of compressible steady and unsteady viscous flows including a computational flow control model. A coupling of these tools and the...
متن کاملImage Motion Estimation using Optimal Flow Control
In this paper we present an optimal control approach for image motion estimation in an explorative and novel way. The variational formulation incorporates physical prior knowledge by giving preference to motion fields that satisfy appropriate equations of motion. Although the framework presented is flexible, we employ the Burgers equation from fluid mechanics as physical prior knowledge in this...
متن کاملOptimal Control of Unsteady Stokes Flow around an Airfoil and the Sensor/actuator Placement Problem
The task of choosing good sensor and actuator locations to control a distributed system can result in search spaces which grow combinatorially. We propose to apply an initial effectiveness filter based on distributed LQR optimal control which can be computed at polynomial cost. This thought experiment, applied to the NACA 0015 airfoil in an unsteady Stokes flow regime, shows that a disturbance ...
متن کاملOptimal Control of Unsteady Stokes Flow Around a Cylinder and the Sensor/Actuator Placement Problem
Effective placement of sensors and actuators is of crucial importance in flow control. Instead of using combinatorial search to identify optimal locations, we pose a related problem of polynomial complexity. If one could sense everything and actuate everywhere, what should one do? Using the unsteady 2D Stokes flow around a cylinder as an example, we obtain the analytic solution of an optimal di...
