Modular multilevel converters (MMCs) have become the most promising converter technologies for medium/high-power applications, specifically for high-voltage direct current (HVDC) transmission systems. For the analysis of the large-scale MMCs-embedded power systems, i.e., multiterminal dc (MTDC) systems and dc grids, modeling and simulation plays an important role in transient and fault analysis. However,...
This paper introduces the binary granule into the algorithm in computing and mining meteorological data. By redefining the binary algorithm, matching operators, convergence operators, disjunction operators, shift algorithm, and the shielding granule are given based on the binary granule. The function of operators is also explained, then different operators are applied on specific computing methods...
Taking consideration of the overall relative efficiency of input-output in emergency response resources in the system and making use of data envelopment analysis(DEA) of dangerous goods accident emergency response vessel to evaluate the efficiency of resource allocation, make the evaluation proceeds with the neural network data for training, and predict the effect of generating program, to obtain...
Electro-hydraulic driving 6-dof parallel robot suffers from non-linearity, strong load coupling disturbance and parameters variations when it moves. In order to solve the problem of precise trajectory tracking for 6-dof parallel robot, a decentralized control strategy was used and a 2-dof QFT robust controller was designed in the joint space of robot. Experiment results show that the 2-dof QFT robust...
Presents evaluation method of indoor environment based on Rough Sets theory for one university library. According to subjective survey results from questionnaire about thermal environment, visual environment, aural environment, air quality environment and spatial environment of the university library, the decision tables are established for knowledge reduction, significances of eleven condition attributes...
