Tube has the curved shape to consider dynamic processes during turning and moving in the vertical plane. The research aims to develop mathematical model allowing to simulate the dynamic of a body suspended by the linear magnetic system with HTS and define the parameters for stable motion inside a tube. Possibility to control the movement of a body using inductor coils on the outside of a tube is also studied. Acceleration by impulse electromagnetic field and deceleration by stationary magnetic field are simulated by the developed model. The proposed configuration of the linear HTS suspension and control systems is relevant for application for high-speed transportation systems.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133134266","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 PR control is adopted to achieve zero steady-state error tracking of voltage reference and to suppress the disturbance of output current. A parameter design method based on the closed-loop dominant pole configuration is given to deal with the high order of PR closed loop system. In addition, this paper proposes an improved control method for parallel-operated inverters. Synchronous control and current sharing control are used to ensure the stable parallel operation with low circulating current. A 2000 VA prototype is built to verify the superiority of the PR control and the feasibility of the parameter design method. The presented parallel-operated strategy can also realize the current sharing between inverters effectively.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130082512","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}

In terms of static and dynamic voltage stability, the most critical bus of IEEE 10-machine 39-bus system has been determined by using sensitivity analysis. The comparison has been made for various wind power penetration levels. It is shown if a large amount of wind power is integrated into power system, the system stability will be deteriorated. In the paper, a static synchronous compensators (STATCOM) is proposed to improve the stability. The calculations and simulations have been conducted by DIgSILENT Power Factory 15.0. Comparative simulation results show that the STATCOM can effectively increase voltage stability margin of the AC system which was considerably decreased due to wind power's penetration.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"13 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114094525","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}

In this study, the principle and the method of image reconstruction which is utilized to generate the cross-sectional images, are briefly introduced. Emphasis is placed on the evaluation of its performance in flow regime identification and cross-sectional void fraction measurement. various flow pattern models are investigated and the corresponding tomographic iamges given.

It is not easy to measure shaft speed directly in some cases. Vibration diagnostic tools can offer an alternative solution to the problem posed by direct rotational speed measurement. Using calculated spectra and cepstra can help to determine rotational speed of stepper motor driven systems easily and accurately. This paper summarizes the theoretical background of discrete spectrum and cepstrum based methodologies and shows results of practical experiments. Equations for each method to calculate the possible speed estimation error are also shown. A novel vibration based hybrid spectral speed estimation logic can be defined, which uses the presented equations to decide which spectral method results in the most accurate output. Numerous vibration measurements have been made to test the hybrid methods reliability. The hybrid spectral speed determination method has been successfully applied on various type of electromotive drives, as well as spark- and compression-ignition internal combustion engines.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132788230","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 piezoelectric ring bender is a less complex, lighter and more reliable alternative to a conventional torque motor. The nozzle flapper valve is used as the only hydraulic control component, rather than a first stage amplifier in traditional servovalves, which allows the whole actuation system to response faster. Due to the lack of flapper displacement feedback, the valve used here is a proportional valve instead of a servovalve in this actuation system. In order to evaluate the performance of the actuator, a system-level mathematical model was built, where the piezoelectric hysteresis effect and the position of the ring bender on the flapper are considered. An analytical solution was implemented by using Matlab/Simulink. Results show that the actuation system proposed in this paper exhibits fast response, good controllability and linearity. A virtual prototype of the actuator is designed to analyze the arrangement. This has potential for use in situations where min load, fast response and high reliability actuation are required.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132884668","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 comparison is based on state-space models of the considered control schemes, which are linearized and utilized for eigenvalue-based analysis. Starting from a comparison of the three schemes with manually tuned controller parameters, it is shown that the current controlled VSM can be unstable for strong grid conditions, while the df/dt-based control becomes unstable when the grid impedance is high. Thus, an iterative tuning algorithm based on eigenvalue parametric sensitivities is applied to investigate how much the time-response and damping of the critical modes can be improved. Limitations to the dynamic performance are identified by participation factor analysis of the critical modes. The results demonstrate that all the investigated schemes can be stable for a wide range of operating conditions, but with inherent differences in the inertial response.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122021830","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}
