Voltage differential feedback control system based on repetitive control is proposed in this paper. The scheme, which can improve the dynamic characteristic and steady state performance by Capacitor voltage as outer loop while its differential as inner loop without current sensor, is achieved on a three-phase PV inverter with TMS320F2808. Two different control strategies, traditional and repetitive...
Community detection has become a fundamental operation in numerous graph-theoretic applications. It is used to reveal natural divisions that exist within real world networks without imposing prior size or cardinality constraints on the set of communities. Despite its potential for application, there is only limited support for community detection on large-scale parallel computers, largely owing to...
In this research, digital 3D ukiyoe was created by using current digital technology for the purpose of evoking many people's interest in ukiyoe that is one of the Japanese traditional culture. In ukiyoe, since the methods of Japanese traditional parallel perspective and Western geometric perspective are used, the layer model and the 3D partial model were used to represent the three-dimensional scene...
For a fluxgate of the time difference type, we can derive the relational expression between the time difference of the fluxgate and the magnetic field which is measured. If we suppose that the core transition time can be ignored, we can get the Mathematical model which the triangular wave and sine wave works as the excitation field, and then calculate the corresponding sensitivity. The results show...
