Current detecting is the key of reactive power and harmonic current compensation, its accuracy and quickness has an important influence on the performance of the compensation. Traditional FBD(Fryze-Buchholz-Dpenbrock) method has a large delay as containing PLL(phase-locked loop) which has a second-order filter. When system voltage drop asymmetric, the phase information would be affected by negative...
According to the application of the dithering signal in Analog-to-Digital Conversion (ADC), this paper proposes an optimum condition of the dithering signal against the nonlinearity of quantization noise in ADC. Theoretical analysis and experimental results indicate that the optimum dithering signal can alleviate the nonlinear characteristics of quantization noise effectively, and reduce the effect...
In this paper, a renovate texture analysis method is proposed. The BEMD is a locally adaptive method and suitable for the analysis of nonlinear or nonstationary signals. The texture image is decomposed to several 2D-IMFs (two dimentional intrinsic mode functions) by BEMD (Bidimentional Empirical Mode Decomposition). Then quaternion is used to get the quaternionic analytic signals, which is compatible...
