In this paper, an obstacle avoidance method for undersea unmanned vehicle (UUV) is proposed. The sensors employed are sonar-based ones, as the other type of sensors, like visual-based sensors, radar-based sensors are not viable for the underwater environments. The deformation of the obstacles has been observed and learnt with the combination of Back Propagation Neural Network (BPNN), and the coordinate position of the obstacle is predicted by the robot. The navigation algorithm applied could navigate the UUV avoiding collisions with the obstacles. The simulation results which could demonstrate the validation of our proposed algorithm are also presented, which are implemented by Matlab.

In this paper, we present a novel quantum neural network (QNN) algorithm enhanced with transfer learning to perform multi-class image classification. The proposed QNN extracts quantum image encoding measurements through the quantum state tomography framework and passes the sampled features through the classical neural network architecture to the proposed learnable parameterized quantum circuit (PQC) followed by gradient update via quantum backpropagation. We benchmark three different PQCs to demonstrate that our proposed algorithm outperforms similar classical CNN architecture in test accuracy on CIFAR10 and MNIST datasets. Present results more prominently establish the success of PQC designs which will be further used in the design of 2D quantum convolutional neural network (QCNN).

GPS-based navigation systems have been developed to support the walking of visually impaired people. However, their use in station premises and malls presented difficulties due to radio wave interference. In such places, an indoor navigation system (IDNS) was indispensable. Recently, an IDNS using geomagnetism that did not require the installation of new infrastructure attracted our attention. It incorporated technology to detect self-position by association with a geomagnetic fingerprint (GMFP) database, which included the geomagnetic vector of the current position, stored in advance on the cloud. However, to realize navigation over an entire floor, a detailed geomagnetic map of the floor was needed, taking a lot of time and labor to measure the geomagnetic field. In this research, we proposed a novel method that limited the area of the GMFP to places above braille blocks and linked the geometric maps to braille block maps. The main features of our system were as follows: (1) Reduction of labor and time required to make the GMFP; (2) Realization of a real-time navigation system with little error in estimated position; (3) A high-resolution geomagnetic map database could be easily made by walking with a nearly fixed stride length without any specific equipment. To confirm the principal operation of our system, we made a prototype system. We then evaluated the performance of our system under various experimental conditions. Finally, we demonstrated a simple navigation system. As a result, we were able to confirm that our system could estimate self-position in real-time with little error and provide simple navigation for visually impaired people.
以gps为基础的导航系统已经开发出来,以支持视障人士的行走。然而,由于无线电波的干扰,它们在车站和商场的使用遇到了困难。在这样的地方,室内导航系统(IDNS)是必不可少的。最近,不需要安装新基础设施的地磁IDNS引起了我们的注意。它结合了与地磁指纹(GMFP)数据库相关联的检测自身位置的技术,其中包括预先存储在云上的当前位置的地磁矢量。然而,要实现整个楼层的导航,需要绘制详细的楼层地磁图,测量地磁场需要耗费大量的时间和人力。在这项研究中,我们提出了一种新的方法,将GMFP的区域限制在盲文块上方,并将几何地图与盲文块地图联系起来。该系统的主要特点是:(1)减少了生产GMFP所需的人力和时间;(2)实现位置估计误差小的实时导航系统;(3)在没有任何特殊设备的情况下,以几乎固定的步幅行走即可轻松获得高分辨率地磁地图数据库。为了确认系统的主要操作,我们制作了一个原型系统。然后,我们在不同的实验条件下评估了系统的性能。最后,我们演示了一个简单的导航系统。因此,我们能够确认我们的系统可以实时估计自我位置,误差很小,并为视障人士提供简单的导航。

This paper establishes a kinematics model for a wall-climbing robot with rear-wheel steering, conducts kinematics analysis, and derives the corresponding formula. Through analysis, it is concluded that the robot's motion trajectory is a combination of a circular arc and a straight line. For the adjustment of different distances and poses, a variety of path planning methods such as arc circumscribed, arc combined with straight lines, and arc inscribed are designed, and the parameter values that need to be determined in each planning method are deduced. In this paper, Matlab software is used for simulation, the expected pose transformation is realized, and the feasibility of the theory is verified. Finally, several path planning methods are compared to determine their respective applicable conditions.

Garlic is one of the main crops the Philippines produce every year. Currently, this is cultivated in the traditional way wherein farmers used soil as its growing medium. A hydroponic system is a new method of planting that has a promising output in a better quality of production. This study focused on the cultivation of garlic as the testing plant in the Ebb and Flow hydroponic system and in the traditional way. An IoT-based monitoring system is also implemented in the study to monitor the pH, Electrical Conductivity (EC), and water temperature of the hydroponic system. The monitoring system used ThingSpeak to store, analyze, and visualize the acquired data by the sensors. As well as the IoT ThingSpeak Monitor Widget to monitor the data in the user’s mobile phone widget. The data that were gathered for the statistical treatment for both the traditional and the hydroponic system are the height of the plant’s leaves for the 20 days after transplant (DAT), 40 DAT, 60 DAT, bulb diameter at 60 DAT, and fresh weight at 60 DAT. Based on the statistical result, it was concluded that the Ebb and Flow hydroponic system has better plant production compared to that of the traditional.

Diagnosis of motor faults plays an important role in the industry to implement preventive maintenance and avoid an unscheduled shutdown. A mechanical fault diagnostic system of a BLDC using the k-NN classification technique with DWT feature extraction is proposed in this study. Voltage signals from healthy and faulty BLDC motors were recorded. The voltage signals of the motors were then decomposed, and features were extracted using the DWT and divided into three data sets which are: training, validation, and testing. The k-NN prediction model was then trained, validated, and tested using a MATLAB environment. The diagnosis was run on 5 different Haar levels. Results showed that Level 1 produced the highest accuracy of 89.510% over the other 4 levels and was statistically verified using ANOVA Test.

Synchronous Reference Frame Method with PLL and Hysteresis Current Controller for Three Phase Shunt Active Power Filter to Mitigate Harmonics Caused by Nonlinear Loads 基于锁相环和滞后电流控制器的三相并联有源电力滤波器同步参考框架方法缓解非线性负载引起的谐波

Rapid growth of power electronic and smart technology used in the industry is one of the key challenges in energy sector. The most common cause of power quality issues in power system is the harmonics which generated by nonlinear loads. Harmonics produce power quality issues and harmful effect on the electrical distribution network. Thus, to improve the power system quality and reliability, it is important to suppress the harmonic distortion cause by nonlinear loads. Traditional passive filters are commonly utilized in the industry but due to its limitation in compensation and production of resonance condition, active power filters are considered the most feasible solution. This study introduces a new design control strategy for Shunt Active power filter (SAPF) using synchronous reference frame (SRF) method for reference current generation, phase locked loop (PLL) and hysteresis current controller to mitigate the harmonic in a three phase distribution system. The design was modelled and simulated using MATLAB/Simulink. The study used IEEE Standard 519-2014 in compliance with the recommended limits of harmonics distortion. A three phase electrical distribution system was modelled and simulated for both balance and unbalance load condition to determine the harmonic distortion caused by nonlinear loads. The proposed SAPF was then connected parallel to the main distribution network to mitigate the harmonics presence in the system. The simulation results validates that the SAPF using SRF with PLL and hysteresis current controller was capable to extract the harmonic currents and generate a compensating current that will be injected back to the line to mitigate the harmonic distortion for both balance and unbalance load condition. Moreover, the results demonstrate that the individual harmonic current distortion are kept within the limit and acceptable harmonic values recommended as per IEEE standard.
电力电子和智能技术的快速发展是能源行业面临的主要挑战之一。在电力系统中,引起电能质量问题的最常见原因是非线性负荷产生的谐波。谐波产生电能质量问题,对配电网产生不良影响。因此,抑制非线性负荷引起的谐波失真对提高电力系统质量和可靠性具有重要意义。传统的无源滤波器在工业上被广泛使用,但由于其在补偿和产生谐振条件方面的局限性,有源电力滤波器被认为是最可行的解决方案。本文介绍了一种新的并联有源电力滤波器的设计控制策略,采用同步参考帧法(SRF)产生参考电流,锁相环(PLL)和磁滞电流控制器来缓解三相配电系统中的谐波。利用MATLAB/Simulink对该设计进行了建模和仿真。该研究使用IEEE标准519-2014,符合建议的谐波失真限制。对三相配电系统进行了平衡和不平衡负荷的建模和仿真,以确定非线性负荷引起的谐波畸变。然后将所建议的SAPF并联到主配电网,以减轻系统中存在的谐波。仿真结果验证了采用带锁相环和磁滞电流控制器的SRF能够提取谐波电流并产生补偿电流,该补偿电流将被注入到线路中,以减轻平衡和不平衡负载条件下的谐波失真。结果表明,各谐波电流畸变均保持在IEEE标准推荐的限值和可接受谐波值范围内。

Avian diseases have been the prevalent cause of shortage in poultry demand. While preventive and control measures can be applied to address this concern, disease identification and verification has been a challenge – especially considering the fact that the modern solutions are costly and are not compatible for remote usage. With this, the researchers proposed the development of a hybrid solar-powered chicken disease monitoring system using decision tree models as the learning algorithm for identification using visual and acoustic inputs from the chickens. The learning algorithm identifies six different symptoms from chickens (slouching, eye foaming, lethargy, feather loss, color paling, and raling) from 15 different chicken samples. Throughout the experimentation of continuous monitoring for 72 hours, the learning model was calculated to have 84.6% accuracy in classifying diseased chickens when only visual imagery is considered, and 86.1% accuracy when audio inputs are also provided. With the integration of the hybrid solar-power system, the system can still continuously operate for 8 hour of power downtime.
禽类疾病一直是造成家禽需求不足的普遍原因。虽然可以采取预防和控制措施来解决这一问题,但疾病的识别和核查一直是一项挑战——特别是考虑到现代解决办法成本高昂,而且不适合远程使用。因此,研究人员提出开发一种混合太阳能鸡疾病监测系统,该系统使用决策树模型作为学习算法,利用鸡的视觉和声音输入进行识别。该学习算法从15个不同的鸡样本中识别出6种不同的症状(无精打采、眼睛起泡、嗜睡、羽毛脱落、颜色苍白和叫声)。在连续监测72小时的实验中,计算出该学习模型在仅考虑视觉图像时对病鸡进行分类的准确率为84.6%,在同时提供音频输入时准确率为86.1%。与混合太阳能发电系统的集成,系统仍然可以连续运行8小时的停机时间。

This paper presents a new approach to control the position of the micro-robotics system with a proportional-integral-derivative (PID) controller. By using Whale Optimization Algorithm (WOA), the optimal PID controller indicators were obtained by applying a new objective function namely, integral square time multiplied square error (ISTES). The efficiency of the proposed WOA-based controller was verified by comparisons made with Grey Wolf Optimization (GWO) algorithm-based controllers in terms of time. Each control technique will be applied to the identified model using MATLAB Simulink and the experimental test facility was conducted using LABVIEW software. The simulation and experimental results show that the performance of WOA-PID controller based on ISTES cost function achieves the best performance among various techniques. Moreover, the WOA technique had the highest performance compared to GWO technique based on rising time, setting time and settling error. Thus, it is recommended to apply WOA for tuning the parameters of PID as it can enhance its performance in micro-robotic systems. It was found that the amount of error is reduced by 47.5% using WOA than other former experiments.
提出了一种利用比例-积分-导数(PID)控制器对微机器人系统进行位置控制的新方法。采用鲸鱼优化算法(Whale Optimization Algorithm, WOA),采用新的目标函数,即积分平方时间乘平方误差(ISTES),得到最优PID控制器指标。通过与灰狼优化(GWO)算法的控制器在时间上的比较,验证了所提出的基于woa算法的控制器的有效性。利用MATLAB Simulink将每种控制技术应用于所识别的模型,并利用LABVIEW软件进行实验测试。仿真和实验结果表明,基于ISTES代价函数的WOA-PID控制器在各种控制方法中性能最好。在上升时间、凝固时间和沉降误差方面,WOA技术的性能优于GWO技术。因此,建议采用WOA对PID的参数进行整定,以提高其在微机器人系统中的性能。实验结果表明,采用WOA方法的误差比以往的实验减少了47.5%。
