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

摘要

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, vents, etc.) are less movable. It is important to note that this approach does not require “time accurate high fidelity simulations” and has been successful in other disciplines such as structural control, control of chemical processes and fluid flow control. We show how these techniques can be applied to high performance building design and control. We present the theoretical basis for the method, discuss the computational requirements and use simple models to illustrate the ideas and numerical methods for solution. We then apply the method results to a multi-zone hospital suite problem.
