In the last decade, the Unmanned Aerial Vehicles (UAVs) industry has a rapid progress in the development and optimization of UAV’s autopilot systems. This paper proposes two flight control methods using the Aerosonde simulation model, which was modeled and simulated using Simulink/MATLAB software. The two methods are a self-tuning PID controller using genetic algorithm and Adaptive Neuro-fuzzy Inference System controller (ANFIS). In a self-tuning PID controller, a PID is genetically controlled and utilized as an autopilot to optimize the controller parameters for the proposed UAV model. However, the second method is based on fuzzy logic controller tuned using neural network. For the main navigation system Three fuzzy logic modules are designed to monitor the altitude, speed and heading angle. Simulation results for the two methods reveal high robustness and durability of ANFIS controller response especially under windy conditions.

This paper reports the results of research on the effect of the surface contour shape of polyethylene insulator on the leakage current and flashover voltage. Three types of insulator surface contour, namely type-A, type-B, and type-C, have been considered. The three contours possess the same creepage distance, but with different fin diameters, so that each type has a different shape factor. The rod-electrode has been used during experiment. The distribution of electric field on each contour type has been observed using finite-element method-based software. Results of experiment showed that all the three considered insulators produced highly inhomogeneous electric field distribution. The highest homogeneity level has been found on the type-A insulator, whereas the least homogeneous field condition has been produced on the type-C insulator. The most homogeneous field on the type-A insulator is related to the lowest shape factor and brings about the lowest leakage current, corona inception voltage, and flashover voltage. The flashover and corona inception voltages could also be improved using the appropriate configuration of upper and lower fins position, which would also lower the insulator leakage current level.

In this paper, a design for a low-noise, low-power, dual-tail dynamic latched comparator is introduced. The input referred noise is reduced through the use of a larger gain comparator dynamic amplifier; a cascode structure is adopted for such an amplifier with a direct effect on the power. To fix this problem without degrading the gain or the input referred noise, bulktuning is applied to the amplifier bias transistor. In addition, a nonconventional power-efficient latch structure is used. Designed in a 130nm UMC process, with a supply voltage of 1.2V and at a clock frequency of 1-GHz, the proposed comparator has an input-referred noise of 290μV, and an input offset voltage of 4.1mV while consuming 100μW of power with a power efficiency of 100fJ/conv. The maximum achievable frequency is 1.25GHz for a differential input 292μ V.

Thermal effect is a key factor affecting laser performance such as the output power and beam quality. In a previous work, a free running and passively Q-switched Nd: YAG laser models were proposed without including the thermal effect. In the validation step of these models, the simulation results do not exactly agree with the published experimental results. It was found out that without including the thermal effect in the laser model the output power of the laser system is overestimated by about 3-6% from its nominal value causes inaccurate calculations of the laser gain and threshold. In this paper, a novel efficient mathematical model for solid-state lasers that includes thermal effects in an enhanced set of laser rate equations is presented. The proposed results help accurate design of solid-state lasers and its cooling systems if required. To confirm the accuracy of the proposed enhanced model, simulation results are compared with the published experimental results and showed good agreement.

In this work, a wideband transmitter leakage cancellation configuration is presented to enhance the isolation between the transmitter and receiver in simultaneous in band full duplex system. The proposed technique incorporates two circulators, one balun, and a wideband power divider. Circulators are usually used to provide isolation between transmitters and receivers However, they are limited in the isolation level, thus, does not provide sufficient receiver protection from transmitter leakage which would decrease signal to noise ratio. In the proposed technique the transmitted signal is equally divided between the 2 circulator, which in-tern provide identical leakage signal. The proposed leakage canceller provides more than 45 dB cancellation over 2 GHz bandwidth from 2 GHz to 4 GHz with a fractional bandwidth of more than 66%. Moreover, a very high isolation level of more than 60 dB is reported from 2.2 GHz to 3.2 GHz with a fractional bandwidth of more than 33%.

Two types of adaptive control are designed for Ultrastick-25e UAV. This is to improve the control response to the Ultrastick-25e. The 1st adaptive autopilot method proposed is self-tuned PID using fuzzy. That is to retune the PID parameter to keep the UAV stable at all operating points. The 2nd adaptive autopilot method proposed is ANFIS controller. It is intelligent control technique. Testing against turbulence of the air, sensor’s noise effect and against the possibility of the model not completing perfectly (uncertainty) are a basic elements for making a comparison between the proposed controllers and evaluate their robustness. Through this paper Adaptive self-tuned PID using fuzzy and ANFIS controllers are used for the first time on Ultrastick-25e UAV. The comparisons between the proposed control systems during several scenarios confirm the robustness of ANFIS controller over the adaptive self-tuned PID using fuzzy.

the aim of this paper is to control for the power system frequency oscillations between interconnected power systems. The first controller used in this study is a fractional order PID (FOPID) controller for load frequency control (LFC) of a single area power system and a three area electrical interconnected power system. For the FOPID controller, besides the proportional, integral and derivative gains Kp, Ki, Kd, there are two more adjustable orders: as the powers of s in integral and derivative actions, viz. $lambda$ and $mu$ respectively. The optimal values of the FOPID (OFOPID) controller parameters (gains and orders) obtained by using Self-adaptive Global Harmony Search (SGHS) technique with an Integral Time Absolute Error (ITAE) objective function. The second controller in this paper is a fuzzy self-tuning optimal FOPID (STOFOPID) controller. The SGHS technique] used to obtain the optimal normalizing gain values of STOFOPID controller. The LFC of the power system investigated with the OFOPID and STOFOPID controllers to improve the frequency oscillation damping in power system. The STOFOPID controller has limited the frequency deviations effectively as compared to OFOPID controllers under different operating conditions, various parameters and various loads in linear and nonlinear power systems. The results carried out using MATLAB/Simulink software.

Communication systems performance over the Ka-band satellite channel is sensitive to the severity of weather conditions, particularly in the event of rainfall, so the use of robust channel coding with superior results is a crucial way to mitigate the effect of rainfall. As satellites are known to have power limitations, it will be efficient to use such strategies but with a decrease in complexity. RSCC Codes are standard forward error correction strategies for space communication systems that can fix errors and endure rainfall but with extra processing time and power consumption for the decoder. In this paper, we are introducing an overview of the rain fade impact throughout Ka-band satellite communication and developing a model of the rainfall fade channel. Besides, we suggest a reduced complexity Viterbi algorithm built upon a modified adaptive Viterbi algorithm. The current work achieves similar error performance as the conventional RSCC and significantly reduces computing loads and memory demands.

The Global Positioning System, GPS customs solutions to determine the coordinates of the GPS receiver location and the receiver clock offset from data extracted from at least four pseudoranges. The constancy and accuracy are essential requirements in positioning calculation. The Least Squares, LS estimate has been widely used for solving GPS positioning problems. Aside its valuable properties, the LS estimate can be affected by outliers which reflect to its performance in terms of accuracy. In this paper, a new approach is applied to LS estimate to increase its accuracy and reliability. Assuming six or more satellites are observed. First, several sets of measurements are formed by making all possible combinations of observed satellites at least five satellites in each set. Second, the LS estimate approach is applied for each set of measurement to estimate the receiver position. A cluster of each set of measurements is obtained and its statistical properties mean and standard deviation are computed. Grubbs’s outlier algorithm is applied to all clusters to find the outlier measurements. The fusion of position data set is based on the fuzzy similarity between the sets of cluster position where the importance weight of each set of data is extracted. According to the proposed algorithm, software is developed using MATLAB. The proposed algorithm is tested, and the position accuracy is improved. Moreover, it reflects the efficiency and feasibility to real-time data processing and monitoring
