For photovoltaic power generation systems, the traditional maximum power point tracking (MPPT) control algorithm has the disadvantages of poor stability and inability to accurately track the maximum power. Therefore, this paper proposes a kind of nonlinear control-backstepping method based on Lyapunov function and fuzzy control to achieve MPPT. This method designs a backstepping controller for the system, and using fuzzy control to obtain the reference voltage of the photovoltaic in the backstepping controller. The topology circuit of the system consists of a photovoltaic panel, a boost circuit, and a load. It’s shown by simulation experiments that the control strategy can effectively reduce the oscillation problem of the photovoltaic power system at the maximum power, alleviate the impact on electronic components in the circuit, and the robustness is stronger.

In order to enhance the receiving and transmitting characteristics and anti-interference the ability of the antenna. It has a great significance to study the circular polarization characteristics of the log-periodic antenna. The linear polarization log-periodic antenna is designed by using the control variable method to change the antenna scale factor and the shortest vibrator length. Circular polarization is realized by using the combination of two pairs of similar linear polarization log-periodic antenna. The optimal result parameters are obtained by simulation, and the circular polarization log-periodic antenna working in L-band with VSWR $lt2.5$ is designed and implemented.

Intrusion detection system(IDS) plays an important role in the cyberspace security. With the rapid development of Internet today, the network traffics to be processed by IDS has many redundant and irrelevant characteristics. Meanwhile, the amount of the network traffics to be processed is very large, which will affect the identification effect of IDS. This paper presents a method which integrates clustering algorithm with support vector machine to improve the accuracy and recognition rate of IDS. Firstly, the preprocessed data is processed by clustering algorithm and divided into several subsets, and then machine learning algorithm is used to model each subset. We compared our method with other state-of-the-art algorithms, and the experimental results showed that our method greatly reduced the training time of the model, and effectively improved the performance of the model.

In this paper, an optimized commutation method based on BP neural network is proposed to solve the problem of slow response, large overshoot and power dissipation caused by algorithm deviation in conventional commutation strategy based on back electromotive force method. Performance of different commutation methods is compared by simulation. Experiment results show that the proposed method can realize a good commutation performance, with a 0.8% power deviation and a 15.906 mean square error compared with ideal condition, which improves 275 times than conventional strategy, 42 times than conventional Neural Network based strategy and has a better stability. The proposed method has better compensation ability for fixed errors such as signal transmission delay, signal filtering delay and motor armature effect at the same time.

Myocardial Infarction (MI) has the characteristics of rapid development and poor prognosis. Early intervention is of great significance in relieving pain and preventing death. For reducing the misdiagnosis rate of MI, a novel classification approach of MI based on a long short term memory (LSTM) is proposed in this paper. Firstly, the original electrocardiogram (ECG) signal is preprocessed, and then it is divided into a heartbeat sequence. Then the heartbeat sequence is input into the deep neural network model for training and learning. Finally, the validity of the method is verified on the Physikalisch-Technische Bundesanstalt (PTB) ECG database. The accuracy of the method is 99.91%. The experimental results show that the classification accuracy of the proposed method is superior to the other methods.

In this paper, the state of charge (SOC) is estimated by charging the battery at constant current and voltage, collecting the current, voltage, temperature and internal resistance during the experiment. The influence of internal resistance on SOC prediction of lithium batteries is mainly considered. In this paper, the Improved BP neural network is used to carry out simulation experiments. The experimental results show that the prediction accuracy is higher and the simulation effect is better than that without considering the internal resistance.

With the increasing demand for logistics in China, the shortcomings of the current short-range logistics field are inefficient, and the occupation of labor is becoming more and more obvious. The proportion of the personnel engaged in production and the transportation personnel who ensure the flow of materials continues to increase, and the production efficiency of the total social labor force continues to decline. In this paper, combined with artificial intelligence related technology, a special drone design scheme is proposed instead of short-distance logistics distributors, aiming at adjusting short-range logistics links, improving logistics efficiency, and optimizing related logistics processes to reduce the need of number of workers to ensure the normal transportation of logistics.

3D integrated circuit (3D-IC) technology gained acceptance due to the ability to achieve extremely high level of integration, where hundreds of ICs are stacked vertically. Such level of integration can result in local power dissipation of more than 50 kW/cm2. This will lead to instant evaporation of the IC, unless an effective cooling technique is employed. Liquid cooling may be one of the most effective techniques for this task. To investigate the effectiveness of this technique, we designed, built and tested a testing platform. The platform includes a testing chip and a cooling module. The test chip contains heaters to provide the power and sensors to measure the local temperature. The study shows that the proposed cooling modules can reduce the temperature for a 420W/inch square circuits to a normal operating range of ICs of 39-50 ˚C, using 2 phase R22 liquid coolant.

In this paper, the influence of inner p-type guard ring (PGR) on the triggering characteristics of diode-triggered silicon-controlled rectifier (DTSCR) is studied. The ESD characteristics of conventional DTSCR with and without inner PGR are measured with the transmission line pulsing (TLP) tester. The results indicate that lower trigger voltage of DTSCR can be obtained by floating the internal PGR, which enhances the current conduction ability of the parasitic SCR in DTSCR essentially. A stronger parasitic SCR can provide a current discharge path with lower resistance before the main SCR is turned on, thus reducing the trigger voltage of the device. Furthermore, two improved structures of DTSCR are also considered, which further confirms the auxiliary triggering effect of parasitic SCR or parasitic PNPNPN structure in these devices.
