An adaptive fuzzy variable structure velocity controller of a permanent magnet linear synchronous motor (PMLSM) is designed for a command profile which has rapid change in a wide range. This is performed for comprehensive nonlinear model of PMLSM including non-idealities such as detent force, parameter uncertainty, unpredicted disturbance, and nonlinear friction. The proposed method is based on the adaptive sliding mode control (SMC) enhanced with a fuzzy inference to determine coefficients of the controller. The fuzzy block uses the desired and real velocity, and also its derivative as three inputs and a and C as outputs. A set of 343 rules come together to make a fuzzy rule base which brings a powerful controller with high resolution for different situations. As an evaluation criterion of the performance of the proposed method, a proportional - integral (PI) controller is designed whose parameters are optimally tuned by the particle Swarm Optimization (PSO) algorithm for better comparison.

Recently, International Center for Global Earth Models (ICGEM) published more than 50 Global Geopotential Models (GGMs). These GGMs plays an important role in a determination of a precise geoid model. Nowadays, some of the models offer high accuracy and better resolution of the gravity field. In this study, several recent GGMs derived from satellite-only (eg. EIGEN) and combined (eg. EGM2008) will be used. Gravity anomalies derived from selected GGMs are analyzed and compared with gravity anomalies derived from terrestrial gravity observation over West Malaysia (WM). The comparison and the results of selected GGMs is shown with the residual statistic. From the results, gravity anomalies derived from combined solution Earth Gravity Model (EGM2008) with the spherical harmonic coefficients up to 2190 is the most suitable model can be use as a reference over West Malaysia.

In this essay a self-oscillating mixer (SOM) is presented fundamental signal generated by the oscillator subcircuit in the mixing process. The core of the oscillator consumes 3mA of current from a 1.8 V DC supply and results in an output power of −0.94dBm per oscillator, and achieved phase noise of −92, −105 and −110dBc/Hz at 100KHz, 600KHz and 1MHz from the carrier, respectively. In the mixing process the presented mixer achieved IIP3 of −8.2dBm with conversation gain of 6.5dB. The circuit was designed and simulated in 0.18-µm CMOS technology by ADS2010.

Changes in stem diameter of orchid plants were investigated in control growing climate. Previous study has focused on stem diameter in relation to plant water on terrestrial plant for outdoor and practice conventional watering by farmers. The objective of this work is to identify the characteristic of orchid stem changes and to relate the stem shrinking rate with orchid plant water content and its microclimate. In this project, strain gauge sensor was employed to measure the changes. Experiments were performed on two different samples of wild orchid, Coelogyne rochussenii and Epidendrum stamfordianum. From the finding, it can relate that changes in voltage strain gauge are related to the stem diameter of orchid plants. In conclusion, single strain gauge can be used in the measurement of the changes in stem diameter orchid plant.

Programmable Logic Controller (PLC) is widely used in manufacturing industries for automation and became one of the essential subjects in the university. Learning theory in class alone is not enough to acquire the knowledge of PLC. Therefore in this paper a PLC Integrated Development Environment (IDE) tool suit is developed to assist students' learning in the class. It consists of ladder diagram editor, simulator and compiler. It also provides an interactive learning in class as well as hand-on activities for laboratories. This software package is developed using Object Oriented Programming (OOP) language Visual Basic 6 to create a virtual microcontroller environment in simulation process.

In this paper a simple method is presented for detecting of zeros location in a linear differential-difference equations with delay by using dominant gain concept and shown that it is much more general and representative than the conventional theory of asymptotic location of zeros. Dominant gain concept states that in a specific frequency band, the dynamic behavior of a quasi-polynomial traces the dynamics of that term in the quasi-polynomial which dominates in its gain with respect to the other term. If it is minimum phase, quasi-polynomial dynamic behavior is minimum phase that means resulting zeros of time delay parameters are in LHP. Also if it is non minimum phase, quasi-polynomial dynamic behavior is non minimum phase that means resulting zeros of time delay parameters are in RHP. This result is very important to design control structure for time delay system.
本文提出了一种利用优势增益概念检测线性时滞微分-差分方程零点位置的简单方法,并证明了该方法比传统的零点渐近定位理论更具普遍性和代表性。优势增益概念指出,在特定的频带内,准多项式的动态行为跟踪准多项式中该项的动态,该项的增益相对于另一项占主导地位。若为最小相位,则准多项式动态行为为最小相位,即时滞参数的零点在LHP内。如果是非最小相位,则准多项式动态行为是非最小相位,这意味着产生的时滞参数的零点在RHP中。这一结果对设计时滞系统的控制结构具有重要的指导意义。

A design of reconfigurable rectangular microstrip slot patch antennas 一种可重构矩形微带槽贴片天线的设计
Pub Date : 2011-06-27 DOI: 10.1109/ICSENGT.2011.5993431

A compact of a reconfigurable rectangular microstrip slot patch antenna of operating frequencies in the range of (2–6) GHz is proposed for Wireless Local Area Network (WLAN) applications. It has one port excited with microstrip line feed mechanism. The proposed antenna consists of a single layer patch antenna with two parallel slots designed that can be controlled via two PIN diode switches. Two parallel slots are incorporated to perturb the surface current path, introducing local inductive effect that is responsible for the excitation of the second resonant mode. By adjusting the status of the switches state either on or off mode in simultaneously, the resonance frequencies can be varied, thus achieving frequency reconfigurable. A comprehensive parametric study has been carried out to understand the effects of various dimensional parameters (slots and PIN diode switches) and to optimize the performance of the antenna. This antenna is capable to achieve return loss less than −10dB and VSWR≤2 in multiband frequencies at 2.4GHz and 5.8GHz when both switches are ON mode while only in 2.4GHz can be achieved when both switches are OFF mode. The designed antennas have been also fabricate onto FR-4 and measured to compare the real results of return loss (S11) and voltage standing wave ratio (VSWR) with those obtained from the simulations. The proposed antenna is very promising for various modern communication applications.
提出了一种工作频率为(2-6)GHz的可重构矩形微带槽贴片天线的结构,用于无线局域网(WLAN)。它有一个用微带线馈电机构激励的端口。该天线由一个单层贴片天线和两个平行的插槽组成,可以通过两个PIN二极管开关来控制。两个平行槽被合并来扰动表面电流路径,引入局部感应效应,负责第二谐振模式的激励。通过同时调节开关的开、关模式,可以改变谐振频率,从而实现频率的可重构。进行了全面的参数研究,以了解各种尺寸参数(槽和PIN二极管开关)的影响,并优化天线的性能。该天线在2.4GHz和5.8GHz的多频带频率下,当两个开关都处于ON模式时,回波损耗小于- 10dB,驻波比≤2,而当两个开关都处于OFF模式时,只能达到2.4GHz。设计的天线也被制作在FR-4上,并测量了回波损耗(S11)和电压驻波比(VSWR)的真实结果与仿真结果进行了比较。该天线在各种现代通信应用中具有广阔的应用前景。

It has one port excited with microstrip line feed mechanism. The proposed antenna consists of a single layer patch antenna with two parallel slots designed that can be controlled via two PIN diode switches. Two parallel slots are incorporated to perturb the surface current path, introducing local inductive effect that is responsible for the excitation of the second resonant mode. By adjusting the status of the switches state either on or off mode in simultaneously, the resonance frequencies can be varied, thus achieving frequency reconfigurable. A comprehensive parametric study has been carried out to understand the effects of various dimensional parameters (slots and PIN diode switches) and to optimize the performance of the antenna. This antenna is capable to achieve return loss less than −10dB and VSWR≤2 in multiband frequencies at 2.4GHz and 5.8GHz when both switches are ON mode while only in 2.4GHz can be achieved when both switches are OFF mode. The designed antennas have been also fabricate onto FR-4 and measured to compare the real results of return loss (S11) and voltage standing wave ratio (VSWR) with those obtained from the simulations. The proposed antenna is very promising for various modern communication applications.","PeriodicalId":346890,"journal":{"name":"2011 IEEE International Conference on System Engineering and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125999131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
