Optimal Sensor and Actuator Placement in Complex Dynamical Networks

Optimal Sensor and Actuator Placement in Complex Dynamical Networks

Controllability and observability have long been recognized as fundamental structural properties of dynamical systems, but have recently seen renewed interest in the context of large, complex networks of dynamical systems. A basic problem is sensor and actuator placement: choose a subset from a finite set of possible placements to optimize some real-valued controllability and observability metr...

H 2 optimal actuator and sensor placement in the linearised complex Ginzburg – Landau system

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 optimal controller, we control a supercritical, infinite-domain formulation of this system. We seek the optimal actuator and sensor placement that minimises the H2 norm of the controlled system, from fl...

Optimal Actuator and Sensor Placement for Active Sensing

In active sensing, actuators are used to impart user-defined energy into a structure from which resulting sensor responses may be mined for useful information regarding the structure’s health. Optimal actuator-sensor placement works to maximize the observability of this information given two primary constraints: the number of actuators and sensors available for the network and the power availab...

Optimization Strategies for Sensor and Actuator Placement

An Optimal Control Approach to Sensor / Actuator Placement for Optimal Control of High Performance Buildings

In this paper we consider the problem of best sensor location for optimal state estimation for real time energy efficient optimal control. Although the basic idea can be applied to the joint sensor / actuator location problem, we focus on the sensor placement because of its immediate application to retrofits where sensors can easily relocated while the location of control inputs (diffusers, ven...
