  • Wiese, Daniel P.; Annaswamy, Anuradha M.; Muse, Jonathan A.; Bolender, Michael A.; Lavretsky, Eugene (2016-03-10)
    This paper presents an adaptive augmented, gain-scheduled baseline LQR-PI controller applied to the Road Runner six-degree-of-freedom generic hypersonic vehicle model. Uncertainty in control effectiveness, longitudinal ...
  • Annaswamy, Anuradha M.; Wiese, Daniel P.; Muse, Jonathan A.; Bolender, Michael A.; Lavretksy, Eugene (2015-04-07)
    This paper presents a new method of synthesizing an output feedback adaptive controller for a class of uncertain, non-square, multi-input multi-output systems that often occur in hypersonic vehicle models. The main challenge ...
  • Wiese, Daniel P.; Annaswamy, Anuradha M.; Muse, Jonathan A.; Bolender, Michael A.; Lavretsky, Eugene (2016-03-09)
    This paper presents a new method of synthesizing an output feedback adaptive controller for a class of uncertain, non-square, multi-input multi-output systems that often occur in hypersonic vehicle models. The main challenge ...
  • Qu, Zheng; Annaswamy, Anuradha; Lavretsky, Eugene (2015-10-07)
    A dominant presence of parametric model uncertainties necessitates an adaptive approach for control of very flexible aircraft (VFA). This paper proposes an adaptive controller that includes a baseline design based on ...
  • Qu, Zheng; Anuradha, Annaswamy (2015-04-07)
    This paper proposes an adaptive controller for a class of multi-input multi-output (MIMO) plants where the number of outputs is larger than the number of inputs, an example of which is very-flexible aircraft (VFA). A ...
  • Nouwens, Oscar; Annaswamy, Anuradha; Lavretsky, Eugene (2015-10-07)
    We examine convergence properties of errors in a class of adaptive systems that corresponds to adaptive control of linear time-invariant plants with state variables accessible. We demonstrate the existence of a sticking ...
  • Soudbakhsh, Damoon; Phan, Linh; Annaswamy, Anuradha; Sokolsky, Oleg (2015-06-28)
    This paper addresses co-design of platform and control of multiple control applications in a network control system. Limited and shared resources among control and noncontrol applications introduce delays in transmitted ...
  • Dibaji, Seyed Mehran; Yildiz, Yildiray; Annaswamy, Anuradha; Chakrabortty, Aranya; Soudbakhsh, Damoon (2017-04-07)
    The purpose of this document is to provide proofs of the results in Dibaji et al. (2017).
  • Soudbakhsh, Damoon; Chakrabortty, Aranya; Alvarez, Francisco; Annaswamy, Anuradha (2015-06-28)
    In this paper we address the problem of widearea control of power systems in presence of different classes of network delays. We pose the control objective as an LQR minimization of the electro-mechanical states of the ...
  • Knudsen, Jesper; Hansen, Jacob; Annaswamy, Anuradha M. (2015-04-21)
    The most formidable challenge in assembling a Smart Grid is the integration of a high penetration of renewables. Demand Response, a largely promising concept, is increasingly discussed as a means to cope with the intermittent ...
  • Annaswamy, Anuradha; Hussain, Alefiya; Chakrabortty, Aranya; Cvetkovic, Milos (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 ...
  • Cvetkovic, Milos; Annaswamy, Anuradha (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 ...
  • Shiltz, Dylan; Cvetkovic, Milos; Annaswamy, Anuradha M. (2015-04-21)
  • Phan, Thao; Annaswamy, Anuradha; Yanakiev, Diana; Tseng, Eric (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 ...
  • Shiltz, Dylan; Annaswamy, Anuradha (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 ...
  • Wiese, Daniel P.; Annaswamy, Anuradha M.; Muse, Jonathan A.; Bolender, Michael A.; Lavretsky, Eugene (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 ...
  • Dibaji, Seyed Mehran; Pirani, Mohammad; Flamholz, David Bezalel; Annaswamy, Anuradha M.; Johansson, Karl Henrik; Chakrabortty, Aranya (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. ...
  • Baros, Stefanos; Shiltz, Dylan; Jaipuria, Prateek; Hussain, Alefiya; Annaswamy, Anuradha M. (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 ...
  • Chang, Wanli; Chakraborty, Samarjit; Annaswamy, Anuradha (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 ...
