Optimization is a mathematical technique that concerns the finding of maxima or minima of functions in some feasible region. There is no business or industry which is not involved in solving optimization problems. A variety of optimization techniques compete for the best solution. Particle Swarm Optimization (PSO) is a relatively new, modern and powerful method of optimization that has been empirically shown to perform well on many of these optimization problems. This paper presents an application of `Particle Swarm Optimization (PSO)' for tuning the parameters of PID controller to achieve system stability. Here the system is two axis robotic arm. PSO algorithm will search for best possible PID controller parameters within its three dimension space of Kp, Ki, Kd. Optimization of peak overshoot (Mp) and settling time (ts) is achieved by using a multi-purpose performance criterion (MPPC). The system is stabilized by minimizing the performance criterion. This paper presents simulation results using MATLAB Simulink to demonstrate tuning of PID controller using PSO along with MPPC gives minimum Mp and ts.
优化是一种数学技术，涉及在可行区域内寻找函数的最大值或最小值。没有哪个企业或行业不涉及解决优化问题。各种优化技术相互竞争以获得最佳解决方案。粒子群优化(PSO)是一种相对较新的、现代的、强大的优化方法，已被经验证明在许多此类优化问题上表现良好。本文提出了一种应用粒子群算法(PSO)对PID控制器的参数进行整定以达到系统稳定的方法。这里的系统是两轴机械臂。粒子群算法将在Kp, Ki, Kd的三维空间中搜索可能的最佳PID控制器参数。利用多用途性能准则(MPPC)实现了峰值超调量(Mp)和稳定时间(ts)的优化。通过最小化性能标准来稳定系统。本文给出了MATLAB Simulink的仿真结果，证明了使用PSO和MPPC对PID控制器进行整定可以得到最小的Mp和ts。

For accurate determination of induction motor (IM) efficiency, precise knowledge of motor losses are required to be known. Stray loss constitute a part of the total loss and hence its detailed analysis and accurate determination is required. Classical IM theory and its equivalent circuit do not consider stray loss in it, resulting in inaccurate performance evaluation. In this work, analysis of the stray losses and its determination using proposed equivalent circuit is done. Finite element method (FEM) is used for core loss analysis and to obtain the stray losses for an inverter fed double cage rotor IM. Stray loss in IM due to loading, presence of harmonics frequency voltage, and slot harmonics is determined by observing core loss increase using FEM. Core material with known core loss data at different frequencies is used. FEM facilitates precise core loss calculation due to the availability of accurate magnetic field density distribution on loading, presence of harmonics frequency voltage and slot harmonics. Individual equivalent resistance each representing stray load loss and stray harmonics loss is determined. A complete equivalent circuit of double cage rotor IM considering the stray loss is then proposed, and its parameters are also determined. This work is applicable for all rotor types in IM. Different components of stray loss with varying load condition is calculated from the proposed equivalent circuit and are compared with those obtained from FEM to validate the results.

In this paper we propose a novel motion vector outlier removal technique for global (camera) motion estimation based on adaptively weighted vector median filtering. The accuracy of motion vector based global motion estimation algorithms is highly dependent on the ability of the system to reject outlier motion vectors. The outlier motion vectors may be due to noise, foreground objects or due to the encoders compression requirements. Our idea is based on the premise that by minimizing the effect of outlier motion vectors, the efficiency of the global motion estimation algorithms can be improved. In our work, the adaptively weighted vector median filter is used to smoothen the motion vector field followed by comparison of the smoothed motion vector field with the input motion vector field to detect the outliers. The detected outliers are then excluded from the global motion estimation process to get a robust estimate of the camera motion parameters. We compare our proposed method with existing outlier rejection techniques using both synthetic as well as real video sequences to show the effectiveness of our proposed method.

A high gain fifth-order boost converter is proposed in this paper. This converter belongs to two switch topology and is capable of giving a higher voltage gain at moderate duty ratios. Firstly, a steady-state analysis is developed for continuous inductor current mode of operation and then various parameter design equations are formulated. For dynamical characterization state-space-models are established and then discrete-time small-signal models are formulated which are then used in the digital controller design procedure. Salient performance parameters of this converter are compared with other fifth-order boost topologies reported in literature. In order to verify the analysis and features of the proposed topology a 24 to 100 V, 100 Watt prototype is considered both in analysis and simulation. Analysis and simulation results are in close agreement with each other.

A typical public health management system has a geospatial context. The public health nodal offices collect the health data from different regions for further analysis. The timeliness and correctness of the collected data is important for public health management. Web based mobile applications may be helpful but it requires constant network connectivity which is often not available in rural regions. This paper proposes a geo-aware SMS or GeoSMS based framework for acquisition of data related to public health management in rural India. This framework is able to acquire public health information along location information. Further, the health data can be integrated with other geospatial layers through enterprise-GIS. An application has been developed to show the efficacy of the proposed framework.

In this paper, we have derived a linear ARMAX model for Nao robot motion, developed by its own manufacturer Aldebaran robotics, called NaoQi walk engine. The model has been obtained assuming robot walking model acts in each direction independently. It has been verified that the whole system works well by the model obtained non-considering the interference between walking model in different directions.

The objective of present work is to improve the epoch estimation performance in high pass filtered (HPF) speech using conventional zero frequency filtering (ZFF) approach. The strength of impulse at zero frequency is significantly attenuated in case of HPF speech and hence shows significant degradation in epoch estimation performance by ZFF approach. Since linear prediction (LP) residual of speech is characterized by sharper impulse discontinuities at epochs location compared to speech waveform, the present work uses LP residual of HPF speech for epoch estimation using ZFF method. The Gabor filtering on LP residual is carried out for further increasing strength of impulses at epochs location of LP residual. The epochs location are estimated by ZFF of Gabor filtered LP residual. The performance of proposed method is better compared to that of existing Hilbert envelope based ZFF approach with improved epoch identification accuracy.

In this paper, we discuss a novel scheme for arriving at a sparse representation and recovery of a class of signals using information theoretic measures. Constituent components containing distinct features of any signal, belonging to a specific class, are separated and represented sparsely in an appropriate fixed basis. The morphological correlation between each of the constituent components and a subset of basis leads to sparse representation of the signal in that basis. The basis is selected using entropy minimization based method which is known to result in coefficient concentration. Simulation studies on speech signals show that in the presence of input noise, the proposed method outperforms conventional methods.

This paper proposed an improved single diode photovoltaic module model over the Rp-model (single-diode, five parameter model) based on datasheet values. Rp-model is widely in use being a compromise among other diode models in simplicity and accuracy. However, the model has major drawback at low irradiance level that is deviation from experimental data in the vicinity of open circuit voltage. And this drawback was improved using two diode model at the expense of increased complexity, parameters, and computation time. The main contribution of this paper is an improved single diode model partly using empirically determined points. Like the Rp-model it has simplicity and improved accuracy, unlike the Rp-model showed a significant reduction in absolute error from the experimental data especially at low irradiance level in the vicinity of open circuit voltage. The performance of model was verified against the experimental data for three common PV module technologies: Mono-crystalline silicon, multi-crystalline silicon, and Thin-film (CIS). The performance of three module types using Rp-model and proposed model was compared against the experimental data. The I-V characteristic and absolute relative error plots of module current revealed the significant improvement of the proposed model over the Rp model.
在rp模型(single-diode, five parameter model)的基础上，提出了一种基于数据表值的改进的单二极管光伏组件模型。rp模型作为一种折衷的模型，在简单性和准确性方面得到了广泛的应用。然而，该模型在低辐照水平下存在较大的缺陷，即在开路电压附近与实验数据存在偏差。使用双二极管模型可以改善这一缺点，但代价是增加了复杂性、参数和计算时间。本文的主要贡献是改进了单二极管模型，部分使用了经验确定的点。与rp模型一样，它具有简单性和准确性的提高，与rp模型不同的是，rp模型显示出实验数据的绝对误差显著降低，特别是在开路电压附近的低辐照水平下。通过对单晶硅、多晶硅和薄膜三种常见光伏组件技术的实验数据验证了模型的性能。将rp模型和所提模型的三种模块类型的性能与实验数据进行了比较。模块电流的I-V特性图和绝对相对误差图表明，该模型比Rp模型有了显著的改进。

New generation of future power system control centers need a paradigm shift in their utility IT operations, coordinated use of applications and the architectural designs to meet new challenges. However, literature on comprehensive architectural design and implementation towards this direction is scarce. In this paper, an architecture design and implementation aspects are demonstrated for integrating applications and for migrating legacy control centers towards future generation smart grid. Appropriate adoption of open standards such as the common information model (CIM) is endorsed. Though the CIM standard is matured at model level, many utilities are facing difficulties in managing data exchanges. As a consequence of the lack of integration capabilities, difficulties are faced in delivering prompt and accurate decisions in response to grid disturbances. Standards-based integration of systems and applications has become imperative. This paper presents an approach for integrating inter-utility and intra-utility application systems through CIM framework. The architecture comprises components for data integration & access, CIM based plug-in adapters and third-party application integration. The details of this architecture along with the intricate relationships between various layers and the open source technologies are described. The proposed architecture includes components such as CIM XML creators, CIM XML database adapters, CIM XML application adapters for power system applications. The applications over this architecture work as web applications. A case study involving WR 400 kV network is illustrated to demonstrate migration strategy. Another case study involving load flow and topology processing applications is illustrated to elaborate the proposed architecture on data from a 400 kV 20-substation state network.
