The proposed six-port (SP) design covers a low frequency wide band ranging from 1.68 GHz to 2.25 GHz with a bandwidth of almost 570 MHz. This low frequency operation is unique to this design, as most of the available designs cover high frequency bands starting above 2 GHz. The frequency bands covered by this design are for commercially available wireless standards. This includes GSM-1800/GSM-1900/PCS (1850~1990 MHz) and UMTS(1885~2200 MHz) bands. A Major contribution of this optimized design results in 40% reduction in the total area comparing its size with the most relevant design. The dimensions of the optimized SP design are suitable to be accommodated within a software defined radio and cognitive radio platforms. Low frequency RF DF and compact size of this design are the key features. Moreover, the proposed system based on SP design can be extended to a variety of applications and other low cost microwave measurements as well. This SP design is realized on a dielectric substrate area of 65 × 65 × 0.64 mm3.","PeriodicalId":103316,"journal":{"name":"MELECON 2014 - 2014 17th IEEE Mediterranean Electrotechnical Conference","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133071749","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 order to facilitate this task, the multi-mass model has been established recently. In fact, for certain industrial drive systems (rolling mills, compressors, etc.), it is necessary to take into consideration the non infinite rigidity of the mechanical link elements which causes mechanical vibrations. These vibrations are a major problem in industry because they harm the system dynamic performances and may end with the deterioration of the system structures. For this purpose, it is useful to dissociate the mechanical part into several masses in order to elaborate the correspondent multi-mass system. This paper presents a linearized model for complex mechanical load based on a two-mass system driven by a DC servomotor and connected together by an elastic link. The first step of the study consists of determining the appropriate transfer functions of the model. Then, linear regulation loops for velocity and load position control are elaborated using PI or PID regulators. As a final step, numerical simulations for different load torques are performed with Matlab/Simulink using the set of parameters of a drive system model. The simulation results show that the regulated system responds conveniently. Further more, these simulations are used to compare the dynamic performances of the different implemented control strategies.","PeriodicalId":103316,"journal":{"name":"MELECON 2014 - 2014 17th IEEE Mediterranean Electrotechnical Conference","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129507296","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}
