title = "The role of control in design: From fixing problems to the design of dynamics",
abstract = "This paper is concerned with the role of dynamics and control communities in the design cycle of new products. The paper advocates the need to change the current role from mainly reactively fixing problems to proactively designing beneficial dynamics early in the design cycle. The message is presented with the aid of a case study involving dynamic modeling (barriers), control (current approach), and design of beneficial dynamics (proposed approach) for mitigating combustion instabilities in jet engines. While the discussion is restricted to jet engines, it is hypothesized that the assessment of the current role and merits of the proposed new role apply broadly across multiple industries.",

note = "Funding Information: This work was partly supported by AFOSR Grants F49620-01-C-0021 and FA9550-04-C-0042, which is gratefully acknowledged. The authors acknowledge help and support from the UTRC dynamics and combustion control team, including Jeff Cohen, William Proscia, Gonzalo Rey, and Karen Teerlinck. Marios Soteriou and Robert Erickson contributed to the work on CFD modeling and reduced order combustion models. The authors would especially like to thank Clas Jacobson, who initiated the work on fundamental limitations and has consistently provided guidance in this area and in control theory in general. Collaboration with Igor Mezic from UCSB influenced various elements of the projects. In particular, methods developed in Mezic and Banaszuk (2004) led to the identification of regions of validity of linear and nonlinear models for thermoacoustic oscillations, and the analysis of the effects of symmetry of DNA molecules on their dynamic behavior ( Mezic, 2005 ) provided insight to the beneficial and detrimental symmetry properties found in jet engines. The authors are additionally grateful to Michael Dellnitz, Mihai Huzmezan, John Guckenheimer, Tim Healey, Mirko Hessel, Tamas Kalmar-Nagy, Jerry Marsden, Troy Smith, Umesh Vaidya and Subbarao Varigonda for numerous conversations on symmetry and dynamical systems. The anonymous reviewers provided valuable suggestions that helped the authors significantly improve the presentation and the readability of this paper.",
