The experimental results indicate that nano-manipulations that are performed in a long time span are not very precise, and often the existence of different error sources, including the tip damage, causes these results to deviate from the intended outcome. In this article, by focusing on the phenomenon of tip damage in the automatic manipulation mechanism, a shape-feedback controller has been introduced to decrease the positioning errors. For this purpose, the tip's root mean squares (RMS) changes have been calculated to use as a criterion of deformation level of tip and particle. Presented shape-feedback controller is a simple and reliable procedure for a more accurate nano-manipulation. At the end, some comparisons are provided for RMS and positioning errors with and without shape-feedback. These comparisons show the applicability and potential of present approach as a controller in automatic nano-manipulation process. Decreasing the positioning errors from 37.77% to 17.77% is the most significant result of this paper.","PeriodicalId":438427,"journal":{"name":"The 2nd International Conference on Control, Instrumentation and Automation","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133619835","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}

Due to the highly nonlinear behavior of the traffic system, and the capabilities of wave-nets in multi-resolution analysis and nonlinear function approximation, the use of the wave-net as a modeling tool for traffic system seems to be very promising. We have also utilized the principle component analysis technique to process the inputs of the network, in order to reduce the network dimension while preserving its accuracy. Because of the time varying nature of the traffic system, the need of an algorithm for updating the model is vital in order to guarantee the performance of the system and the control strategies. Hence, in this work we have used online L2 learning algorithms to update the model. Simulation results, which are based on the real traffic data, demonstrate the increased efficiency of the online model compared to the offline model without update.","PeriodicalId":438427,"journal":{"name":"The 2nd International Conference on Control, Instrumentation and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130392782","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}

The motor optimization is achieved using a modified harmony search technique, though other optimization methods can also be used. The expressions of motor electromagnetic torque, speed, voltage, current, power losses, volume and cost are analytically represented as functions of motor geometric parameters. The objective function is a combination of motor power losses, volume and cost, and needs to be minimized subject to a set of electrical and mechanical requirements and limitations. Ten design parameters are considered including the number of poles, current density and the dimensions of magnet, stator, rotor, winding and air-gap. The effects of each design parameter on the brushless DC motor performance have been investigated. The method was originally conceived for the design of a small motor for a biomedical application, but in this paper one sample case of a larger motor illustrates the general use of the technique.","PeriodicalId":438427,"journal":{"name":"The 2nd International Conference on Control, Instrumentation and Automation","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116892787","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}

Considerable research activities have been carried out so far in this field in order to disclose the secrets behind the nonlinear behaviour of these systems. Although the results of the research in this area have been satisfactory so far, it seems that there is no end to the efforts for performance optimization of gas turbines. A variety of analytical and experimental models as well as control systems has been built so far for gas turbines. However, the need for optimized models for different objectives and applications has been a strong motivation for researchers to continue to work in this field. This paper is aimed at presenting a general overview of essential basic criteria that need to be considered for making a satisfactory model and control system of a gas turbine. GT type, GT configuration, modelling methods, modelling objectives as well as control system type and configuration are the main preliminary factors for modelling a gas turbine which will be briefly discussed in the paper. Some of the research in this field will be also stated shortly.","PeriodicalId":438427,"journal":{"name":"The 2nd International Conference on Control, Instrumentation and Automation","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131082872","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}

Therefore, how to minimize the energy consumption while maintaining an extended network lifetime becomes the most critical issue when it comes to the design of the mobile base station for the wireless sensor networks. Sensor nodes nearby to the sink disperse large amount of data to the sink with less energy consumption while the nodes far away from the sink require more energy to do the same. A key advantage of incorporating mobile sinks into the design of a sensor network is that it may enable the gathering of timely information from remote deployments and may also potentially improve energy efficiency. The best position to locate the sink is determined at begining of each round and then sink move to based onrandom waypoint model.","PeriodicalId":438427,"journal":{"name":"The 2nd International Conference on Control, Instrumentation and Automation","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131084045","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}

Because of importance and existence of faults that don't have a known structure in control system, i.e., fault occurred because of tangle of complex factors, In this paper a Lipschitz nonlinear system with unmeasured states and unknown faults is considered and a novel FDD architecture for it is presented. A neuro/fuzzy model consisting of few locally linear models (LLMs) with on-line updated centers and width vectors is used to approximate the model of the fault. A nonlinear observer is used to estimate the states of the system that are inputs to LLMs. The stability analysis of system is carried out via Lyapunov theory, from which the parameter updating rules are derived.

The observer overcomes the drive system model uncertainties and unknown parameters to recover the drive system chaotic states form a scalar noisy coupling signal. Using the appropriate adaptation low the unknown parameters of the drive system are estimated and used to boost the state estimations. In addition, drive system state noise, channel noise, and measurement noise, are considered and the system and observer are modeled via stochastic differential equations. Stochastic stability of the drive-response system is proved through several theorems. These theorems guarantee that the mean values of the state estimation errors converge to zero as time goes to infinity. In the observer the adaptive sliding mode gains are always nonsingular even when the estimation error goes to zero. Presented numerical simulations confirm the effectiveness of the proposed observer and chaos synchronization scheme.","PeriodicalId":438427,"journal":{"name":"The 2nd International Conference on Control, Instrumentation and Automation","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128330305","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}

Then, the stabilization of system is improved via dynamic state-feedback controller. In fact, the proposed condition is a criterion which results in increase of regions of stabilization for such systems. This result is in the linear matrix inequality (LMI) framework which can be solved easily by using the existing standard numerical software.
