The internet service is provided by a given number of servers located in the main node of internet service provider (ISP). In some cases; the overload problem was occurred because a demand on a given website goes to very high level. In this paper, a fuzzy logic control (FLC) has proposed to distribute the load into the internet servers by a smart and flexible manner. Three effected parameters are tacked into account as input for FLC: link capacity which has three linguistic variables with Gaussian membership function (MF): (small, medium and big), traffic density with linguistic variables (low, normal and high) and channel latency with linguistic variables (empty, half and full); with one output which is the share server status (single, simple and share). The proposed work has been simulated by using MATLAB 2016a, by building a structure in the Fuzzy toolbox. The results were fixed by two manners: the graphical curves and the numerical tables, the surface response was smoothly changed and translates the well-fixed control system. The numerical results of the control system satisfy the idea of the smart rout for the incoming traffics from the users to internet servers. So, the response of the proposed system for the share of server ratio is 0.122, when the input parameter in the smallest levels; and the ratio is 0.879 when the input parameters are in highest level. The smart work and flexible use for the FLC is the main success solution for most of today systems control.

In order to shorten the wireless charging time of electric vehicles (EVs) and achieve stable charging, an adaptive smart control method for EV wireless charging is proposed in the paper. The method dynamically tracks the rechargeable battery state during the whole charging process, realizes multi-stage charging of constant current (CC) or constant voltage (CV) by switching two kinds of compensation networks of bilateral L3C and L3C-C, and regulates the charging voltage and current to make it as close as possible to the battery charging characteristic curve. This method can be implemented because the voltage source connected to the coupler and the compensation networks of bilateral L3C and L3C-C have the CC and CV source characteristics, respectively. On the basis of the established adaptive smart control system of EV wireless charging, the experiments of wireless data transmission and adaptive smart charging were conducted. The results showed that the designed control system had a response time of less than 200 ms and strong anti-interference ability and it shortened the charging time by about 16% compared with the time using traditional charging methods, thereby achieving a fast, stable, safe, and complete wireless charging process.

Conventional PID control system of Direct Current (DC) servo motor is only suitable for the system which Mathematical models can be precisely expressed [1] And it can’t meet the demand of the nonlinear and time-varying system. In the paper, a control system based on fussy-PID is proposed. The basic algorithm of the fussy-PID is introduced firstly. And then the design of the fussy-PID control system is introduced. The results of the experiments have shown that the fussy-PID control system improved the performance of the DC servo motor..

The application of smart control technology to both aging and new infrastructure is essential to extending service life, increasing life safety, and decreasing repair and replacement costs. One area of control technology research for civil engineering structures that has received little attention historically is that of high-impact loads, such as collision events. The dissipation of impact energy using smart control devices, such as magnetorheological (MR) dampers, leads to less plastic deformation and damage, and a lower likelihood of collapse in civil engineering structures. Due to the short duration and high variability in magnitude of potential impact loads, the issue of sub-optimal controller performance arises. In order to boost controller performance and improve the effectiveness of the control system, a radar-based impact load identifier is proposed. This radar-based impact load identifier will be used to estimate impact loads from imminent impacting objects, for example vessels and trucks, thus providing input information to the control system before the impact actually occurs. This paper presents the characterization and validation, through laboratory tests, of one part of the radar-based impact load identifier, the range and velocity estimation of the incoming moving objects. The range and velocity information are then used to direct structural control based on laboratory impact tests. An ultrawideband monostatic pulsed radar is used for range and velocity measurements of a laboratory-scale impacting vehicle. The range and velocity measurements obtained from the radar scans are verified using physical measurements and control testing. The tests showed great accuracy for both range and velocity with less than 3% error for each measurement and demonstrated structural control based on these measurements. It is shown from control system testing that the proposed approach is effective in reducing the structural impact responses by 11–30%, depending on the performance index, for pre-impact structural stiffening with passive control of MR dampers.

With river water sources for use as fisheries, it can provide alternative livelihoods for people on the side river of the Kemuning river. However, if they use fishery media such as keramba, the water source of the Kemuning river will overflow in the rainy season, besides that if you use a pond, you need a land medium that is less possible.The use of a kolam terpal is one solution to this problem. This pool is made based on the need for a portable pool because it has a radius of 1.5m and a height of 1.5m. Kolam terpal are fish farming using tarpaulin materials as an alternative to soil or concrete ponds. The pool with the base and the sides of the walls is made of tarpaulin. The tarpaulin needed to make this pool is a type of tarpaulin with a material that is pressed so that no leakage occurs. The implementation of this tarpaulin pool using biofloc techniques and by using solar power makes this pool easier to adapt. This tool is equipped with solar panels and an automatic control system. The use of solar panels by utilizing the abundance of solar power and minimizing the expenses of fish farmers without electricity bills to activate pumps for water needs and pond air aerators. In addition, with the biofloc technique, the fish farming mechanism becomes more efficient.The targets and outputs generated from this program, especially for partners, are: the fulfillment of alternative livelihoods with fish farming, and an increase in income of approximately 80%, there is a biofloc kolam terpal equipment with solar panel technology. Keywords: Tarpaulin pool, solar power, bioflok AbstrakWarga di pesisir aliran anak sungai kemuning daerah Kelurahan Loktabat Utara belum memanfaatkan aliran anak sungai sebagai sumber usaha perikanan. Dengan sumber air sungai untuk pemanfaatan sebagai usaha perikanan dapat memberikan alternatif mata pencaharian bagi warga di pesisir aliran anak sungai kemuning. Akan tetapi jika menggunakan media perikanan seperti keramba, sumber air anak sungai kemuning dapat terjadi luapan jika dimusim hujan, selain itu jika menggunakan kolam tambak membutuhkan media lahan yang kurang memungkinkan. Penggunaan kolam terpal menjadi salah satu solusi untuk mengatasi masalah tersebut, kolam ini dibuat berdasarkan kebutuhan akan kolam yang portabel karena ukuranya jari-jari 1,5m dan tinggi 1,5m. Kolam terpal merupakan budidaya ikan dengan menggunakan bahan terpal sebagai alternative kolam tanah atau beton. Kolam yang dasarnya maupun sisi-sisi dindingnya dibuat dari terpal. Terpal yang dibutuhkan untuk membuat kolam ini adalah jenis terpal dengan bahan dipres sehingga tidak terjadi kebocoran. Implementasi kolam terpal ini dengan menggunakan teknik bioflok serta dengan menggunakan tenaga surya maka kolam ini dapat lebih mudah diadaptasikan. Alat ini dilengkapi dengan panel surya dan sistem kontrol otomatis. Penggunaan panel surya dengan memanfaatkan limpahan tenaga surya dan meminimalkan pengeluaran para pembudidaya ikan tanpa adanya tagihan listrik untuk mengaktifkan pompa untuk kebutuhan air dan aerator udara kolam. Selain itu dengan teknik bioflok, mekanisme pembudidayaan ikan menjadi lebih efisien.Target dan luaran yang dihasilkan dari program ini khususnya untuk pihak mitra adalah: terpenuhinya alternatif mata pencaharian dengan budidaya ikan, dan meningkatkan pendapat kurang lebih 80%, terdapat peralatan kolam terpal bioflok dengan teknologi panel surya. Kata kunci: Kolam terpal, tenaga surya, bioflok
