      Adaptive Control of Linear Time-Varying Plants: A New Model Reference Controller Structure 

      Tsakalis, Kostas S.; Ioannou, Petros A. (1989)
      In this paper we study the problem of developing a control law which can force the output of a linear time-varying plant to track the output of a stable linear time-invariant reference model. We first show that the standard ...

      Adaptive LQ control with anti-windup augmentation to optimize UAV performance in autonomous soaring applications 

      Kahveci, N. E.; Ioannou, Petros A.; Mirmirani, M. D. (2008)
      The performance of a glider can be considerably improved by means of soaring and optimization of its trajectory. Recent advances in the area of static soaring assume known linear glider dynamics and no actuator saturation ...

      Adaptive mode suppression scheme for an aeroelastic airbreathing hypersonic cruise vehicle 

      Levin, J.; Ioannou, Petros A.; Mirmirani, M. D. (2008)
      This paper presents an adaptive mode suppression scheme that is simulated on a longitudinal model of a generic airbreathing hypersonic flight vehicle. An aerodynamically optimized vehicle model is used which has a long ...

      Adaptive mode-suppression and disturbance-rejection scheme with application to disk drives 

      Levin, J.; Ioannou, Petros A. (2009)
      The goal of a track-following controller for a disk drive is to maintain as close to perfect tracking as possible. Better tracking allows for more data to be stored on a single disk. There are several factors which make ...

      Adaptive notch filter using real-time parameter estimation 

      Levin, J.; Pérez-Arancibia, N. O.; Ioannou, Petros A. (2011)
      The control of flexible systems is often difficult due to the exact frequencies of the elastic modes being hard to identify. These flexible modes may change over time, or vary between units of the same system. The variation ...

      Adaptive quadratic functional estimation of a weighted density by model selection 

      Petsa, A.; Sapatinas, Theofanis (2010)
      We consider the problem of estimating the integral of the square of a probability density function f on the basis of a random sample from a weighted distribution. Specifically, using model selection via a penalized criterion, ...
