For the design of the three-phase buck-type SWISS rectifier controller, the model construction is not precise enough and the precision is low. The fuzzy PI control is introduced and compared with the traditional PI control. First, the working principle of the PFC circuit of the Buck-type SWISS rectifier is analyzed. Then the control structure and the design process of the system are given, the paper introduces the design of the traditional PI double closed loop controller and the fuzzy control law of fuzzy PI control? and the simulation experiment is carried out at the end. Theoretical analysis and simulation results show that the design of the control system in this paper is reasonable, the power factor is high, and the current harmonic content at the input side is low, and a stable low ripple voltage output can be achieved. Moreover, the static and dynamic performance of fuzzy PI control is better than that of traditional PI control, and it has better rapidity and robustness.

The results of this study are as follows: Based on the growth data of Micropterus Salmoides in intensive aquaculture base, a growth model is proposed. Due to the limited conditions in the actual growth process, it is impossible to weigh each fish too often frequently. Therefore, the first step is to interpolate the weight data of each fish every half a month. The second step is to use the growth curve to fit the interpolated weight data. The second step is to use the growth curve to fit the interpolated weight data and calculate the growth model. The third step is to test the validity of the model with test data and to decide the choice of the model. The experimental results showed that the model we calculated accords with the growth pattern of Micropterus Salmoides under culture conditions is effectual.

Rcommendation system can solve the information overload in mass data and recommend content that users are interested in. User similarity calculation is a common recommendation algorithm, but the traditional algorithm only considers the similarity between user-item ratings and ignores the influence of users' inherent characteristics. This paper presents an algorithm combining user feature similarity and user-item rating similarity, and proposes to use F1 indicator to evaluate the efficiency of the recommendation algorithm. The hexperimental results show that the improved algorithm can effectively improve the recommendation effect.

SAR image processing is an important way to detect marine oil spills. The detection efficiency and accuracy are the most important indicators. In order to detect oil spills more efficiently, a framework based on features and the extreme learning machine method is proposed in this paper. Texture feature is an effective approach for region of interest extraction in image processing, which is consistent with human visual sense. Both gray level co-occurrence matrix and Tamura features are selected to extract features from SAR images, which is different from general methods with denoising and image segmentation procedure. Then, a feature vector is constructed including all the features extracted, and the vector is taken as the input to train an extreme learning machine model. Through the training of many samples of SAR images, a final model for oil spill detection will be accomplished. A lot of detection experiments using this model show that the oil spill detection framework based on feature and extreme learning machine has higher accuracy and efficiency, and it can be carried out in practical application.

To build an efficient data processing module in TLD tracking algorithm, the samples of foreground targets and the background were compressed by using a very sparse measurement that can extract the features by a non-adaptive random projections efficiently, and after the sparse representation, the dimensionality reduction data can preserve most of the salient information and allow almost perfect reconstruction of the signal. Building a real-time long-term tracking system based on the sparse representation could improve the efficiency of tracking algorithm, thereby solving the problem of efficiency decline in TLD with the time going. In our algorithm, the sparse representation combines with the three sub-tasks of tracking task: tracking, learning and detection, which can not only guarantee the ability of estimating errors, but also improve the efficiency of data processing.

This paper mainly studies the method of water meter plum pin precise positioning, and proposes a positioning method of water meter plum blossom needle with high positioning accuracy, anti-jamming performance and versatility. The method firstly uses the three-frame difference method to obtain the contour area of the plum blossom needle dynamically, secondly the convex hull algorithm to extract the boundary information of the plum blossom needle, and then uses the minimum encircling circle algorithm to create the circumscribed circle of the plum blossom needle. By traversing the distance between each vertex and the circumcircle pixel, we find the exact coordinate position and achieve the precise positioning of the plum blossom needle. The test results show that the precision of the water meter can reach 97.46%-99.133% by accurately positioning the plum blossom needle. On the one hand we can accurately locate the plum blossom needle with the bubble inside the dial, on the other hand, this method covers the shortage of the traditional photoelectric pulse verification method which can only detect the water meter of the plum blossom needle at the same position.

Steam system is an important part of nuclear power plant. And test method is usually required to verify the system technical plan during the design stage. For effective simulation of steam export features at steam generator secondary side under dynamic conditions in a large-scale steam test project, two boundary control schemes of PID closed-loop and open loop were proposed. A simulation model of the test system was established using the two-phase modeling tool JTopmeret. In the early stage of the test, the simulation model was optimized and verified based on system thermal test data, and the accuracy and reliability of the simulation model were confirmed. Based on the revised simulation model, two boundary control schemes were compared. The open loop control scheme with better outcomes was confirmed as the control scheme of the final test. The simulation results provided effective guidance for the final test, as well as strong support for the successful accomplishment of the test.

large-scale global coverage is an important application scenario in 5G communication. Global information interconnection of satellite mobile communication is realized regardless of regional restriction. It is necessary to use modulation system of higher frequency efficiency to realize high-throughput communication. The system data throughout can be increased through application of OFDM. Due to the high PAR (peak-to-average ratio) of OFDM, high power return is generated. Meanwhile, Doppler effect results into intersymbol interference of OFDM. OFDM satellite communication channel estimation algorithm based on training queue is proposed based on foregoing problems. Firstly, the basic theory of OFDM and satellite communication is introduced to provide basis for further analyzing the adaptability of OFDM to the satellite communication system. OFDM modulation based on satellite communication system is designed including serial-to-parallel conversion and, coding mapping, inverse fourier transform, parallel conversion and up-conversion of satellite communication OFDM. The design of training queue of satellite OFDM is optimized to realize correlation peak detection, mark space and frequency deviation estimation and improve the channel estimation performance of satellite OFDM.
