Model predictive control (MPC) methods are widely used in permanent magnet synchronous motor (PMSM);however, How to minimize the impact of system delay and motor parameter perturbation on the operation of PMSM is the key to constrain the MPC. To address the problem of current disturbance caused by system delay and motor parameter perturbation, we will propose a series of sliding modes to suppress current disturbances caused by above reasons. Besides, The PMSM model is used to analyse the causes of system delay. Then, the current disturbance caused by parameter perturbation is introduced into the adaptive sliding mode control algorithm for suppression, and the relevant theoretical proof is given. Finally, the effectiveness of the overall scheme is verified through simulations. © 2023 IEEE.

Composing music for video is essential yet challenging, leading to a growing interest in automating music generation for video applications. Existing approaches often struggle to achieve robust music-video correspondence and generative diversity, primarily due to inadequate feature alignment methods and insufficient datasets. In this study, we present General Video-to-Music Generation model (GVMGen), designed for generating high-related music to the video input. Our model employs hierarchical attentions to extract and align video features with music in both spatial and temporal dimensions, ensuring the preservation of pertinent features while minimizing redundancy. Remarkably, our method is versatile, capable of generating multi-style music from different video inputs, even in zero-shot scenarios. We also propose an evaluation model along with two novel objective metrics for assessing video-music alignment. Additionally, we have compiled a large-scale dataset comprising diverse types of video-music pairs. Experimental results demonstrate that GVMGen surpasses previous models in terms of music-video correspondence, generative diversity, and application universality.

W-band (75-110 GHz) is a potential radio frequency band to provide long-distance wireless links for mobile data transmission. In this paper, high-speed wireless transmission at W-band based on photonics-aided method, including optical heterodyne, photonics-aided down-conversion without RF oscillator and coherent detection, is proposed and demonstrated experimentally. Then the photonics-aid method is compared to the conventional electronic method using solid state electronic devices, for the first time. It is indicated the photonics-aided method has the advantage of lower harmonic components, spur, less nonlinearity and no local oscillator leakage, so the photonic-aided W-band mm-wave transmitter shows 2.5 dB better performance than the electronic one. For the receiver, the photonics-aided method can outperform the electronic method, with the help of larger electro-optical modulator bandwidth and lower drive voltage at the photonic down-conversion part. Finally, a recorded equivalent transmission distance of 29km@84GHz and 45km@75.6GHz is achieved respectively for 1Gbaud QPSK signal with the help of photonics-aided method. © 2024, The Authors.

The contours of objects effectively represent essential 3D information such as shapes and boundaries. Existing contour detection methods mostly rely on thresholding or neural networks to classify points as edge or non-edge points. However, these methods often lack generalization ability on datasets with different shapes, leading to issues such as missing contours and discontinuous distribution. To address this, we propose a 3D point cloud contour generation method based on the denoising diffusion probabilistic model (DDPM). Our method treats the complete point cloud as an explicit condition to guide the generation of contour from noise. Specifically, our method trains the DDPM to be a conditional generative network customized for contour generation tasks. In the network, we design the Conditional Feature Extraction (CFE) module that obtains multi-scale feature information, and the Conditional Feature Fusion (CFF) module embeds this information in the generation process to guide contour generation. The experimental results demonstrate the effectiveness of our method. The source code of our method is available at: https://***/djzgroup/ContourGeneration.
