In recent years, with the increasingly widespread application of unmanned aerial vehicle (UAV), the network technology of UAV has also caused for concern. In this paper, according to the background of related technologies of UAV, a mobility prediction clustering algorithm (MPCA) relying on the attributes of UAV is proposed. The dictionary Trie structure prediction algorithm and link expiration time...
To improve the dynamic performances of permanent magnet synchronous motor (PMSM) drive, a novel implementation of speed controller based on adaptive fuzzy logic is presented in this paper. Using the output of the fuzzy speed controller (FC), the quadrature axis current reference value can be obtained. At the same time, the outputs of the current controller can be corrected by the disturbance voltage...
Direct torque control based on space vector modulation (SVM-DTC) preserve DTC transient merits, furthermore, produce better quality steady-state performance in a wide speed range. A new adaptive neural integration algorithm for estimating stator flux is introduced. The simulations of conventional DTC and the proposed control topologies are given and discussed. It is concluded that the proposed control...
For permanent magnet synchronous motor (PMSM) direct torque controlled (DTC) drive, stator resistance variation and conventional hysteresis controller will bring high flux linkage and torque ripples inevitably. In order to solve this problem, the implementation of direct torque controlled drive for permanent magnet synchronous based on neural networks and multi fuzzy controllers is presented, which...
