Non-linear models obtained using Newtonian mechanics are linearized using small perturbation theory and converted to state space models. These models are implemented in Matlab/Simulink and simulation results are obtained. The different types of control techniques implemented for these models include Linear Quadratic Regulator (LQR), Linear Quadratic Gaussian (LQG) control and Linear Matrix Inequalities (LMIs). These control strategies significantly improve performance of these models.","PeriodicalId":414131,"journal":{"name":"2017 International Conference on Open Source Systems & Technologies (ICOSST)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129551946","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}

Array feed network is a design with an equal power divider for four elements array. Simulation results shows that VSWR is equal to 1.03, which means that power reflection loss is equal to −36.43dB. Hence, the radiation efficiency achieved is −0.95dB. The results also demonstrated that this simple design lowers the side lobe level more than −20dB in both planes. The simulated gain is 13 dB at the central frequency f0 while it's higher than 13 dB for a frequency band of 1.4 GHz. The simulation is done on CST microwave studio software.","PeriodicalId":414131,"journal":{"name":"2017 International Conference on Open Source Systems & Technologies (ICOSST)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114267576","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}
