With the development of underwater vehicle technology, the application of underwater target detection ranges from ocean search, rescue and detection to fishing for marine products. At this stage, the main problem for seafood detection is the slow detection processing time caused by a large number of parameter calculations in deep learning networks. This paper proposes a lightweight underwater target detection network based on YOLOv5s. First, GhostBottleneck is used to reduce the network parameters. Second, a convolution block attention mechanism is added to the last layer of the backbone network to increase the weight of the valuable features while suppressing invalid features to improve detection accuracy. Finally, GIoU- NMS in YOLOv5s replaces DIoU-NMS, which enhances the detection accuracy of the network for clustered overlapping targets. The results show that the lightweight network parameters and floating point calculation are 36.11% and 43.63% less than those of YOLOv5s, the FPS is 109.12, and the detection accuracy is increased by 1.53%. Fast and efficient detection considerably improves the efficiency of underwater seafood detection. © 2023 Technical Committee on Control Theory, Chinese Association of Automation.

An algorithm for shape reconstruction and size measurement of spherical particles is proposed by combining interferometric particle imaging (IPI) with deep learning. Simulated and experimental interferometric defocus images of spherical particles are obtained from the optical transfer matrix theory and the IPI system. The Respe-Unet++, which adds Residual blocks (Res) and the Patch Expand (PE) module to U-net++, is proposed to reconstruct images containing shape and size information. The method is validated through simulation and experiments. The results indicate that Respe-Unet++ achieves a relative error of 0.00278% and a standard deviation of 0.071 in particle size measurement, with a measurement speed of 53.38 FPS. The analysis of incomplete images shows a relative error of 0.13% at a ratio of 10%. Compared to other U-net-based architectures, the Respe-Unet++ demonstrates superior performance in size measurement.

The Adaptive Disturbance Rejection Control (ADRC) is widely used in nonlinear systems such as Permanent Magnet Synchronous Motors (PMSM) due to its adaptability, strong robustness, and ease of implementation. However, traditional ADRC performs poorly in high-order nonlinear systems, as its performance mainly depends on the nonlinear function representing the total disturbance. To address this issue, this paper proposes an improved ADRC based on the Compensation Function Observer (CFO). The CFO belongs to the type III system, exhibiting significantly improved signal processing performance compared to the type I Extended State Observer (ESO), and it can attenuate the influence of the nonlinear function in the compensation stage. Additionally, in order to alleviate the difficulty of parameter tuning in ADRC, fuzzy control is introduced in the error feedback loop. The feasibility of the proposed method is verified by establishing a Matlab/Simulink simulation model. The simulation results demonstrate that, compared to traditional ADRC, the new ADRC exhibits better response speed and disturbance rejection for common signals. © Beijing Paike Culture Commu.

Thispaper introduces a novel hybrid communication system employing a combination of asymmetric clipped optical orthogonal frequency division multiplexing (ACO-OFDM) and on-off keying (OOK) modulation schemes. The proposed method of signals reconstruction eliminates the need for additional bias current and avoids excess power consumption. At the transmitter, asymmetric signals reconstruction and secondary clipping ensure the transmission signals remains non-negative. Additionally, a layered transmission system is proposed to improve the system's spectrum utilization rate. These hybrid systems enable simultaneous transmission of OFDM and OOK signals, independent recovery of both signals at the receiver, this flexibility supports various quality of service requirements. Simulation results demonstrate successful recovery of both OOK and OFDM signals at the receiver. © 2024 IEEE.
