The second-order nonlinear state equations are established to describe the dynamic behavior of the stator voltage. Then the direct stator voltage control based on the second-order auto-disturbance rejection control (ADRC) is proposed for the rotor side converter. The total disturbance is observed and compensated in real time by ADRC; and the constant amplitude and frequency of stator voltages are...
To solve the problem of poor anti-noise performance of the traditional fuzzy C-means (FCM) algorithm in image segmentation, a novel two-dimensional FCM clustering algorithm for image segmentation was proposed. In this method, the image segmentation was converted into an optimization problem. The fitness function containing neighbor information was set up based on the gray information and the neighbor...
