Two time-scale model based adaptive control method is proposed for a helicopter to overcome wind disturbances in this paper. Wind disturbances are considered as a mixture of four sinusoidal signals with unknown frequencies, amplitudes and phases. The controller is designed based on the concept of time-scale separation, which has the advantage of decoupling of the rotational and translational dynamics...
A vast number of medical imaging protocols identify anatomical regions of interest (ROI) from two dimensional (2D) localizer images to aid high resolution scan planning. These localizer scans are typically two dimensional projections of three dimensional data and as such have lower image detail due to overlapping tissue. The problem is further complicated by large variations in shape, size, appearance...
This paper investigates the automatic control problem of high speed train systems under immeasurable aerodynamic drag. Robust and adaptive control algorithms are developed to ensure high precision tracking of train position and velocity. The control scheme does not rely on precise system parameters. Furthermore, there is no need for analytic estimation or experimental determination of resistance coefficients...
