An adaptive homo‐backstepping control for nonlinear strict‐feedback systems subjected to unknown actuator dead‐zone and disturbance is investigated. A sliding‐mode‐based integral filter is constructed and used to approximate the desired feedback control in the backstepping‐like recursive design technique. Subsequently, the problem of “explosion of complexity” is solved by obviating the analytic derivatives...
Sparse representation has been extensively studied in the signal processing community, which surprisingly pointed out that one target signal can be accurately represented as a linear combination of very few measurement signals, often called atoms, in a given dictionary. This discovery has soon been employed to the field of pattern recognition and more recently, given rise to a newly developed unsupervised...
Independent Component Analysis (ICA) is a new signal processing technique that can recover source signals from the observed mixtures. In some applications of ICA, it is desired that the order of the recovered source signals can be predicted and the component which we are interested in can be extracted separately. But the order of recovered source signals is unpredictable. Facing this problem, a new...
In this paper, the test voltage injection coupled with tracking of magnetic saliencies created by saturation and rotor slotting was used for shaft sensorless speed control of induction motor drives at zero and low speed. Method does not require additional wire connections and is usable for star or delta machine connection. The paper is proposing low memory method of elimination saturation effect from...
