Foundations of Infrastructure CPS
(2015-10-07)Infrastructures have been around as long as urban centers, supporting a society’s needs for its planning, operation, and safety. As we move deeper into the 21st century, these infrastructures are becoming smart – they ... -
Frequency Control using Cooperative Demand Response through Accumulated Energy
(2015-10-07)This paper proposes a hierarchical control architecture for engaging demand into providing primary frequency response services. The proposed architecture relies on the use of information about accumulated energy for the ... -
A Model-based Dynamic Toll Pricing Strategy for Controlling Highway Traffic
(2015-10-07)A model-based approach to dynamic toll pricing has been developed to provide a systematic method for determining optimal freeway pricing schemes. A novel approach is suggested for alleviating congestion, which utilizes ... -
A Practical Integration of Automatic Generation Control and Demand Response
(2015-10-16)For a power grid to operate properly, electrical frequency must be continuously maintained close to its nominal value. Increasing penetration of distributed generation, such as solar and wind generation, introduces ... -
Sequential Loop Closure Based Adaptive Autopilot Design for a Hypersonic Vehicle
(2016-03-09)This paper presents a sequential loop closure approach to designing a velocity and altitude tracking au- topilot for a hypersonic vehicle. The control architecture consists of two decoupled control subsystems, one for ... -
Squaring-Up Method for Relative Degree Two Plants
(2015-09-28)Abstract--- Non-square multi-input-multi-output (MIMO) plants are becoming increasingly common, as the addition of multiple sensors is becoming prevalent. However, square systems are needed sometimes as an leverage when ... -
Supplementary Materials to "Adaptive Output-Feedback Control for A Class of Multi-Input-Multi-Output Plants with Applications to Very Flexible Aircraft"
(2016-03-22)A dominant presence of parametric model uncertainties motivates an adaptive approach for control of very flexible aircraft (VFA). This paper proposes an adaptive controller that includes a baseline design based on observers ... -
Supplementary Materials to "Adaptive Output-Feedback Control for Relative Degree Two Systems Based on Closed-Loop Reference Models"
(2015-09-14)Abstract--- In this paper, a new adaptive output-feedback controller for multi-input-multi-output (MIMO) linear plant models with relative degree two is developed. The adaptive controller includes a baseline design based ... -
A Systems and Control Perspective of CPS Security
(2019-01-22)Abstract—The comprehensive integration of instrumentation, communication, and control into physical systems has led to the study of Cyber-Physical Systems (CPS), a field that has recently garnered increased attention. ... -
Towards Resilient Cyber-Physical Energy Systems
(2017-03-14)In this paper, we develop a system-of-systems framework to address cyber-physical resilience, the ability to withstand the combined presence of both cyber attacks and physi-cal faults. This framework incorporates a definition ... -
Utilization-Aware Adaptive Back-Pressure Traffic Signal Control
(2015-10-07)Back-pressure control of traffic signal, which computes the control phase to apply based on the real-time queue lengths, has been proposed recently. Features of it include (i) provably maximum stability, (ii) low ...
