Enabling resilience of complex engineered systems using control theory
Yodo, Nita; Wang, Pingfeng; Rafi, Melvin (IEEE, 2018-03)Successful recovery from a disrupted state to maintain optimal performance is a key feature that a resilient complex engineered system should have. In the engineering design community, the current focus of engineering ... -
Kalman-Filter-Based Adaptive Control: flight testing on general aviation aircraft
Rafi, Melvin; Steck, James E.; Watkins, John Michael (American Institute of Aeronautics and Astronautics, Inc., 2017-09)Sensor noise and turbulence effects have been prevalent issues in control system design. Although a control system may respond well to “clean” input signals and commands in simulation, this may not be the case when a ... -
Laplace-based predictive estimation of loss-of-control boundaries on a transport aircraft
Rajaram, Kiran; Rafi, Melvin (Wichita State University, 2017-04-28)Loss-of-control events are the greatest contributing factor to accidents amongst commercial aircraft. In this research, an approach to predicting the onset of loss of-control events is developed using a Laplace-based method, ... -
