A comprehensive predictive strategy was proposed for the neutral-point balancing control of back-to-back three-level converters. The phase currents at both sides and the DC-link capacitor voltages were measured for the prediction of the neutral-point current. A quality function was found to balance the neutral-point, and a metabolic on-times distribution factor was used as a predicator to minimize...
A novel arithmetic is proposed for calculating the lower conservatism degree of robust stability for the linear uncertain systems with system matrix being interval matrix based on the theory of Gerschgorin separating the eigenvalues of matrix. And the new method transformed the arithmetic about the lower conservatism degree of robust stability for linear uncertain systems into the feasibility of the...
A new control method for active power filters using support vector machine (SVM) is presented. In the strategy, SVM is employed to model and predict future harmonic compensating current, it has the advantages of nonexistence of local minima solutions, automatic choice of model complexity and good generalization performance. Based on the model output, Genetic algorithm optimization method is adopted...
Communication using power line as a medium of signal transmission offers a convenient and inexpensive solution for multimedia signal transmission and control applications. This paper aims to present a de-noising scheme which is a combination between chaotic spread spectrum sequence system and the wavelet transform in power line communications (PLC). The proposed communication scheme is based on two...
