Global Positioning System (GPS) is affected by several factors such as measurement technique, environmental effects on the measurements, positioning solution, etc. Among these factors, identifying an optimal measurement technique is considered significant because an improper measurement technique provides a diverging solution. In this paper, one static positioning algorithm (i.e., Lease Square Estimator) and one kinematic positioning algorithm designated as Correntropy Extended Kalman Filter (CEKF) are proposed for precise GPS applications like Category-I (CAT-I) aircraft landings. The proposed algorithm uses correntropy criterion (CC) as an optimal criterion, a local similarity measure, unlike Minimum Mean Square Error (MMSE). Also, it uses an iterative approach called fixed point algorithm for renovating the rearward estimates. The simulation results show that the proposed algorithm outperforms the static positioning algorithm in 2-dimensional and 3-dimentsional surface.
全球定位系统(GPS)受测量技术、测量环境影响、定位方案等因素的影响。在这些因素中,确定最佳测量技术被认为是重要的,因为不适当的测量技术会提供发散的解决方案。本文针对一类(CAT-I)飞机着陆等精密GPS应用,提出了一种静态定位算法(即Lease Square Estimator)和一种运动定位算法(即相关扩展卡尔曼滤波(CEKF))。与最小均方误差(MMSE)不同,该算法使用相关系数准则(CC)作为最优准则,即局部相似性度量。此外,它还使用一种称为不动点算法的迭代方法来更新后向估计。仿真结果表明,该算法在二维和三维平面上均优于静态定位算法。

The present work considers the application of an observer based control system to the observation and control of biomass concentration in a hybrid bioreactor system in the presence of measurement delays. A Proportional Integral (PI) controller was used and the performance of the system was assessed in terms of the maximum sampling intervals for fixed values of delays and maximum allowable delays for particular sampling partition diameters. The results obtained were analysed relative to a previous work which considered a feedback linearising controller to perform the same funtions. A comparative study was carried out to determine the superiority of the new controller for this application. The PI controller provided better responses and allowed the observer to converge at relatively higher values of sampling time and delays.

This paper proposed the implementation of decision tree classifier on FPGA. A comma separated value format is accepted by the framework and then it does many steps to form a trained model. Subsequently the framework forms two formats of decision tree based classifier viz Joint Photographic Experts Group and Verilog/VHDL. The hierarchy of generated tree is represented by JPEG (image) representation and VHDL /Verilog code is used as a the representation of trained model hardware description. The current framework uses the Verilog/VHDL in FPGA DESIGN VALIDATION FLOW. The novelty framework bridges the gap between M.L. model training and its hardware designing.

A review on control techniques of the Wind Power Generation (WPG) using Doubly Fed Induction Generator (DFIG), integrated to the microgrid/utility grid, has been presented, in this paper. The DFIG contains a three-phase back-to-back Voltage Source Converter (VSC), which has two converters such as Rotor Side Converter (RSC) and Grid Side Converter (GSC). The RSC has been aimed to control stator flux, to deliver reactive power to DFIG, and to track maximum power generation by the WPG. The GSC is targeted to balance the active power of WTG system, and maintain the voltage of dc link of back-to-back VSC. The modelling of WTG system has also been presented for developing its fast response controllers. The controllers of the back-to-back VSC have been widely designed using a rotating d-q synchronous reference frame. For validating the reviewed control strategies, a smart microgrid consisting of WPG system, second generating system as photovoltaic system, and load, has been presented under grid connected mode. The validation test is conducted in the MATLAB environment.
本文综述了双馈感应发电机(DFIG)风力发电与微电网/公用电网集成的控制技术。DFIG包含一个三相背靠背电压源转换器(VSC),它有两个转换器,如转子侧转换器(RSC)和电网侧转换器(GSC)。RSC旨在控制定子磁通,向DFIG输送无功功率,并跟踪WPG的最大发电量。GSC旨在平衡WTG系统的有功功率,并维持背靠背VSC直流链路的电压。为开发WTG系统的快速响应控制器,对WTG系统进行了建模。背靠背VSC的控制器被广泛地设计为使用旋转的d-q同步参考系。为了验证上述控制策略的有效性,在并网模式下,提出了一个由WPG系统、作为光伏系统的二次发电系统和负载组成的智能微电网。验证测试在MATLAB环境下进行。

Ansys Apdl 2021 R2 software has been used to design the Magnetorheological Damper or commonly known as MR damper. To get a better 3D shape of MR damper the software is being commonly used. To continue the designing process of this damper, B-H curve MR fluid 132 DG from Lord Corporation has been collected to observe its rheological change. Ansys Apdl 2021 R2 software learning is necessary to start the design and perform its finite element analysis. Finite element or FEM is necessary to demonstrate a clear data on fluid and air gap of the designed MR damper and also for having a real magnetic flux density and intensity value. All the materials used in this MR damper has its own relative permeability. After analyzing the rheological diversity of MR fluid 132 DG relative permeability of each component has been measured. Normally, five different ferromagnetic and magnetic components are kept in this MR damper and some insulators also being kept in this damper. MR damper which is commonly seen in different kind of semi-active devices to control its unnecessary noise and vibration. No other damper in this era shown as much capability like MR damper. After defining every area of the MR damper with concerned calculation, meshing has been done to see and correct every single partition and gap of the fluid and material. Going through the entire research it was prime concern how the MR damper behave according to shear stress. So, magnetic flux density vs. shear stress and vice versa has been analyzed to learn its capability in traditional business. Wire gauge of the MR damper kept as short as possible to avoid decays. Boundary condition of the MR damper has been seen in ANSYS software to ensure the current flow and to see direction of flowing electron. Current value from 0.1 to 1.5 has been continuously calculated to get its numerical value and its magnetically comparison with shear stress. Magnetic flux density and also magnetic flux intensity area has been found after the Nodal analysis of this damper. Vector diagram implementation is necessary to gain the fluid flowing area. The designed MR damper are also capable for controlling vibration of tall buildings from earthquakes and thunderstorm. Also, different kinds of application rather than these are also kept in mind. Leg postulates consumers can also be helpful with this. After all, by shaping the magnetic flux density and intensity we got the desired 3D shape of MR damper.
采用Ansys Apdl 2021 R2软件设计磁流变阻尼器或俗称MR阻尼器。为了获得更好的磁流变阻尼器的三维形状,该软件是常用的。为了继续该阻尼器的设计过程,收集了Lord公司的B-H曲线MR流体132 DG,观察其流变变化。Ansys Apdl 2021 R2软件学习是开始设计和执行其有限元分析所必需的。为了得到所设计磁流变阻尼器的流体和气隙的清晰数据,并获得真实的磁通密度和磁强值,需要进行有限元分析。磁流变阻尼器所用的所有材料都有其相对磁导率。在分析了核磁共振液流变多样性的基础上,测量了各组分的相对渗透率。通常情况下,五种不同的铁磁性和磁性元件被保留在这个磁流变阻尼器中,一些绝缘体也被保留在这个阻尼器中。磁流变阻尼器常用于各种半主动装置,以控制其不必要的噪声和振动。在这个时代没有其他阻尼器显示出像MR阻尼器一样多的能力。在确定磁流变阻尼器的每个区域并进行相关计算后,进行网格划分,以查看和校正流体和材料的每个分区和间隙。在整个研究过程中,主要关注的是MR阻尼器在剪切应力作用下的性能。因此,本文分析了磁通密度与剪切应力的关系,以及剪切应力与磁通密度的关系,以了解其在传统业务中的应用能力。磁流变阻尼器的线规尽可能短,以避免衰减。在ANSYS软件中得到了磁流变阻尼器的边界条件,以保证电流的流动和电子的流动方向。连续计算0.1 ~ 1.5的电流值,得到其数值及其与剪应力的磁性比较。通过对阻尼器的节点分析,得到了阻尼器的磁通密度和磁通强度面积。矢量图的实现是获得流体流动面积的必要条件。设计的磁流变阻尼器还能控制高层建筑在地震和雷暴中的振动。此外,不同种类的应用程序,而不是这些也要记住。莱格认为消费者在这方面也能有所帮助。最后,通过对磁通密度和磁强的整形,得到了期望的磁流变阻尼器的三维形状。

In this paper, a solar photovoltaic (PV) array powered scalar control of the induction motor (IM) drive for the water pumping application is presented. This control scheme involves the standalone operation of the IM drives. Solar PV array has nonlinear I- V characteristics, it requires additional control technique for Maximum Power Point (MPP) tracking. The efficiency is improved with the help MPP tracking (MPPT) technique which extracts maximum power available to the PV array. Perturb and observe (P&O) control technique offers simple control, ease of implementation and low cost is utilized along with DC/DC converter. This Stage extracts maximum power available from the PV array and fed power to the next stage of the DC/AC converter. The switching of DC/AC converter is generated with the help of open-loop V/F control of IM. The performance of the system is examined with the help of MATLAB/Simulink and corresponding results are present to support the suitability of the control scheme.
本文提出了一种太阳能光伏阵列供电的异步电动机标量控制水泵驱动系统。这种控制方案涉及IM驱动器的独立操作。太阳能光伏阵列具有非线性的I- V特性,需要附加的最大功率点跟踪控制技术。利用MPP跟踪(MPPT)技术提取光伏阵列可用的最大功率,提高了效率。摄动和观察(P&O)控制技术提供简单的控制,易于实现和低成本与DC/DC转换器一起使用。该阶段从光伏阵列中提取最大功率,并将功率馈送到DC/AC转换器的下一阶段。DC/AC变换器的开关是借助IM的开环V/F控制产生的。利用MATLAB/Simulink对系统的性能进行了测试,并给出了相应的结果来支持控制方案的适用性。

This paper provides the implementation of indirect design approach of IMC-PID controller based on PSO algorithms. In indirect design approach a plant G (s) is shifted by a constant parameter ψ. Then an IMC-PID controller is designed for the shifted version of the plant G(s -ψ). Gains of the PID controller is depends on the only one unknows Parameters ψ when the plant parameters are known. Here is an assumption that the plant parameters are known. Particle Swarm optimization is also used for determining the optimized values of ψ for PID controller. Proposed method also does not use any IMC filter, and it provides less settling time, minimum overshoot, less integral absolute error (IAE) and increases the robustness of the system.
本文提出了一种基于粒子群算法的IMC-PID控制器间接设计方法的实现。在间接设计方法中,工厂G (s)被一个常数参数ψ移位。然后设计了一种IMC-PID控制器来控制移位后的G(s -ψ)。当对象参数已知时,PID控制器的增益依赖于唯一一个未知参数ψ。这里假设工厂参数是已知的。粒子群算法还用于确定PID控制器的ψ的最优值。该方法不使用任何IMC滤波器,稳定时间短,超调量小,积分绝对误差小,提高了系统的鲁棒性。
