Benchmark problem: an air brake model for trains

This paper proposes a simplified hybrid model of a freight train equipped with an air brake. The control of such a system and the enforcement of numerous safety constraints constitute a relevant benchmark to evaluate tools for proving safety …

Models and Control Strategies for Data Center Energy Efficiency

This dissertation considers data centers as CPSs, with a focus on run-time management and operating costs. The proposed modeling framework explicitly captures the cyber- physical nature of data centers and allows the development of models that …

A Cyber-Physical-System Approach to Data Center Modeling and Control for Energy Efficiency

This paper presents data centers from a _cyber-physical system_ (CPS) perspective. Current methods for controlling information technology (IT) and cooling technology (CT) in data centers are classified according to the degree to which they take into …

Models and Control Strategies for Data Centers in the Smart Grid

This chapter discusses the challenges and the possibilities offered by controlling a data center as a node of the _smart-grid_. The communication between the grid and the data center takes the form of a time-varying and power-consumption-dependent …

Model Predictive Control of Data Centers in the Smart Grid Scenario

This paper discusses the challenges and the possibilities offered by controlling a data center as a node of the smart-grid. Communication between the grid and a data center takes the form of a time-varying and power-consumption-dependent electricity …

A cyber-physical systems approach to energy management in data centers

This paper presents a new control strategy for data centers that aims to optimize the trade-off between maximizing the payoff from the provided quality of computational services and minimizing energy costs for computation and cooling. The data center …

A Unified Thermal-Computational Approach to Data Center Energy Management

This paper presents a unified, coordinated, thermal-computational approach to the data center energy management problem. A data center is modeled as two coupled net-works: a computational and a thermal network. The first network describes the …

Reducing Data Center Energy Consumption via Coordinated Cooling and Load Management

This paper presents a unified approach to data center energy management based on a modeling framework that characterizes the influence of key decision variables on computational performance, thermal generation, and power consumption. Temperature …
