The grid-connected current output from a flyback photovoltaic microinverter is prone to distortion due to nonlinear factors such as switching tube dead zones, driving asym-metry and grid voltage disturbances. Aiming at the traditional PI control which cannot effectively improve the influence of nonlinear factors, this paper proposes an interleaved flyback photovoltaic microinverter based on PI and repetitive control, and in-depth research on the circuit topology, control strategy and the design method of the PI and repetitive controller of this inverter is carried out. Simulation results show that the Photo-voltaic micro-reverse grid-connected current with PI and repet-itive control is of high quality, with better dynamic performance and anti-interference capability, while realizing the maximum power point tracking. © 2024 IEEE.

Tomato is an important vegetable species, also known as tomato. However, it is often jeopardized by invasive diseases, resulting in lower eating quality and yield impacts. The traditional method of detecting pests and diseases mainly relies on manual visual observation, which is more dependent on past experience, and the subjective factors have a greater impact, so the actual effect is not accurate and less efficient. In this paper, we explore a tomato pest and disease detection mobile robot for the detection of pest and disease conditions during tomato cultivation in greenhouse environment. The mobile visual inspection robot uses STM32 microprocessor as the core of the mobile control system, and the FreeRTOS operating system is transplanted to complete the robot's autonomous walking, position detection and other tasks;equipped with the NLE-AI800 artificial intelligence board at the same time using the YOLOV5 modeling framework for the target diagnosis as well as the board end deployment. © 2024 IEEE.

A moving sound signal separation method based on the sparse representation of Doppler atoms is proposed to address the interference problem of wheel rail contact noise in the process of collecting train bearing signals. Using a single microphone to collect sound signals, first Doppler modulation is performed on dictionary atoms;Then perform sparse matching decomposition on the acoustic signal to obtain the sparse signal;Finally, the signal reconstruction theory is used to separate the sound source and obtain the bearing signal. Through experimental signals, it has been proven that under the influence of Doppler effect, the proposed method can effectively extract the target sound source and has good in band noise cancellation effect. © COPYRIGHT SPIE.

In the operating rooms and the intensive care unit, it is crucial to manage the patient's hemodynamic status, which includes factors like cardiac output and mean arterial pressure. Anesthesiologists confront a difficult task while monitoring high-risk patients. Cardiac output optimization has been found to enhance the result of high-risk patients in terms of hospital stay, mortality rate, post-operative problems, etc. The application of standard control approaches is restricted because the mean arterial pressure response of a patient using vasoactive medicines is modeled by a first-order dynamical system with time-varying parameters and a time-varying delay in the control input. In order to circumvent implementation challenges, this work develops an approximation technique that describes the system using a higher-order model. Predictive control is therefore used to comprehend the practical application of higher-order hemodynamic systems. The effectiveness of this strategy is demonstrated by the simulations and outcomes that are given. © 2023 IEEE.

Based on time series data collected by the ZPW-2000A track circuit detection vehicle, which detects the induced voltage of compensating capacitor, this paper presents a method for predicting compensating capacitor faults using the MFO-LSTM prediction model. Specifically, an induced voltage sequence is established based on the section and month, and an LSTM network, optimized by the Moth-flame optimization algorithm, is employed to identify the induced voltage variation over time and predict the fault of the compensated capacitor induction voltage over a given period. Experimental results demonstrate that the proposed model can accurately fit the induced voltage curve, with small error, providing valuable technical support for maintenance of railway compensation capacitors. © 2023 IEEE.
