In order to improve the calculation accuracy and speed of distribution networks state estimation, this paper presents a robust algorithm of three-phase state estimation for distribution networks based on residual prediction. All kinds of measurements in distribution networks are used in the algorithm, jacobian matrix becomes constant though phase transform of node voltage and branch current, and equivalent...
Successive interference cancellation (SIC) has been extensively applied to estimate transmit signals in communication systems. When the channel state information (CSI) and noise statistics are imperfectly estimated, the standard SIC estimators that ignore the model mismatch may perform poorly. This paper introduces regularized SIC estimation to provide robustness against the model mismatch. Suboptimal,...
It is important to detect and recognize the traffic sign for mobile robot localization and navigation. In this paper, an algorithm frame of feature detection and matching has been developed which includes shape detection, Harris corner detection, SIFT feature matching and robust estimation method. Firstly, the color threshold segmentation algorithm in RGB color space is adopted to get the candidate...
