A real-time simulation for the Cascaded STATCOM fully implemented on field-programmable-gate-arrays (FPGA) is proposed in this paper. The switching-function model for the STATCOM is employed, where the IGBTs and diodes are taken as ideal switches, to reduce the amount of calculation. With the help of external circuit calculation, the operation in dead-time period is taken into consideration, which...
We present a digital watermarking algorithm for 3D model which is based on encrypted holographic digital watermarking algorithm to protect the embedded watermark information (such as a specific identity of the copyright information, etc.) and to improve the security and robustness of the digital watermark information. Firstly, the watermark image is processed by the double random phase modulation...
In view of the motion process simulation and path planning for mechanic arm, this paper presents a visualized simulation method based on inverse kinematics. Based on Inverse kinematics of multi-joint mechanic arm and 3D simulation model technology, the whole motion process simulation has been solved, which can provide reference standards for the mechanic arm selection and the motion planning in automatic...
