The selection and placement of actuators and sensors to control compressible viscous flows is addressed by developing a novel methodology based upon the eigensystem structural sensitivity of the linearized evolution operator appropriate for linear feedback control. Forward and adjoint global modes are used to construct a space of possible perturbations to the linearized operator, which yields a small optimization problem for selecting the parameters that best achieve the control objective… 

Optimal sensor and actuator placement for feedback control of vortex shedding

Abstract We consider linear feedback control of the two-dimensional flow past a cylinder at low Reynolds numbers, with a particular focus on the optimal placement of a single sensor and a single

Sensor and actuator selection for feedback control of fluid flows

The present thesis regards linear estimation and control for two fluid flows, with a particular focus on the placement of sensors and actuators. In the first part of the thesis, we study the complex

Sensor and actuator placement trade-offs for a linear model of spatially developing flows

We consider feedback flow control of the linearised complex Ginzburg–Landau system. The particular focus is on any trade-offs present when placing a single sensor and a single actuator. The work is

Data-driven sensor placement for fluid flows

Optimal sensor placement for fluid flows is an important and challenging problem. In this study, we propose a completely data-driven and computationally efficient method for sensor placement. We use

Reinforcement-learning-based control of convectively unstable flows

Real-time feedback stall control of an airfoil at large Reynolds numbers using linear genetic programming

Machine learning control is applied in real-time to an airfoil equipped with variable-velocity jets and pressure sensors in a closed-loop wind tunnel. The objective of the control is to improve the

Reinforcement-learning-based actuator selection method for active flow control

Abstract This paper addresses the issue of actuator selection for active flow control by proposing a novel method built on top of a reinforcement learning agent. Starting from a pre-trained agent

Reduced-order control using low-rank dynamic mode decomposition

LrDMD stabilizes the Ginzburg–Landau system with a lower- order controller and is able to suppress vortex shedding from an inclined flat plate at a cost lower than either DMD or OMD, and yields an improved estimate of the adjoint system, for a given rank, relative to DMD and OMD.

Controller selection and placement in compressible turbulent flows By

Deciding how and where to control a fluid system often relies heavily on intuition, experience, and what actuators are readily available. While useful for flows for which experience exists, adopting

Linear feedback control and estimation of transition in plane channel flow

Modern linear control theory has recently been established as a viable tool for developing effective, spatially localized convolution kernels for the feedback control and estimation of linearized

The linearised complex Ginzburg–Landau equation is a model for the evolution of small fluid perturbations, such as in a bluff body wake. By implementing actuators and sensors and designing an H2

Linear optimal control applied to instabilities in spatially developing boundary layers

The work presented extends previous research on linear controllers in temporal channel flow to spatially evolving boundary layer flow. The flows studied are those on an infinite swept wedge described

The adjoint of the perturbed and linearized compressible viscous flow equations is formulated in such a way that its solution can be used to optimize control actuation in order to reduce

Sensitivity analysis and passive control of cylinder flow

A general theoretical formalism is developed to assess how base-flow modifications may alter the stability properties of flows studied in a global approach of linear stability theory. It also

This review article addresses the dynamics and control of low-frequency unsteadiness, as observed in some aerodynamic applications. It presents a coherent and rigorous linearized approach, which

Flow Control: The Future

The subject of e ow control, particularly reactive e ow control, is broadly introduced, leaving some of the details to other papers in this special volume of the Journal of Aircraft . The ability to

The stability of nonparallel flows is considered using superposition of global modes and it is found that a wave packet is optimally excited by an initial condition consisting of localized backward leaning Orr structures.

DNS-based predictive control of turbulence: an optimal benchmark for feedback algorithms

To achieve flow relaminarization in the predictive control approach, it is shown that it is necessary to optimize the controls over a sufficiently long prediction horizon T+ [gsim], which represents a further step towards the determination of optimally effective yet implementable control strategies for the mitigation or enhancement of the consequential effects of turbulence.
