As the module temperature increases, the voltage of the module decreases. This leads to a reduction in the overall output power. As a result, the modeling of operating PV module temperature is important to investigate the climatic factors which affect the PV module temperature. This paper presents the modeling of operating PV module temperature using an Artificial Neural Network (ANN) with solar irradiance and ambient temperature set as the ANN inputs. Besides that, Cuckoo Search (CS) was employed to determine the optimal number of neurons of the ANN hidden layer, learning rate and momentum rate such that the Mean Absolute Percentage Error (MAPE) of the modeling is minimized. CS was found to outperform an Artificial Bee Colony (ABC) algorithm in optimizing the ANN parameters during training by producing lower MAPE.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131509201","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}

During tracking only position measurements are considered to be available. A pseudo velocity signal is generated using a filter to compensate for the velocity signal. A Lyapunov function has been utilized to prove the stability of the closed loop system. The controller ensures Uniformly Ultimately Bounded stability of the system states. Simulation results prove the effectiveness of the proposed controller.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130520486","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}

However, the subsystem objective functions in existing BLISCO methods may be mutually coupled again caused by the step of calculating partial derivatives of the original objective with respective to the shared coupled variables, and thus prevent the parallelization of the subsystem optimization. In this paper, the quasi-separable MDO problem form is introduced and an improved BLISCO method based on this form is proposed to tackle this problem. At last, one mathematical example and one engineering problem are used to test the feasibility, accuracy and efficiency of the improved BLISCO method.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116434614","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}

With board-level clock frequencies in the above 100MHz to 500MHz range, the first few harmonics are within the common communications bands of TV, FM radio, cell phone, and PCS. This means there is the very real possibility of electronic products interfering with communications unless their electromagnetic emissions are kept below acceptable levels. Therefore, EMC issues over 100MHz are of particularly high interest to the experts. However, what is the below 30MHz?

For modelling the liquid fuel sloshing we combined the general free-floating robot dynamics with a mechanical pendulum equivalent model. For the dynamic parameter identification we extended our identification algorithm for rigid body systems to account for these two effects. The flexible and sloshing modes are excited only with the manipulator executing optimized trajectories. For the identification algorithm we make use of the robotic joint position and torque sensor data as well as of on board GNC sensor data. Numerical simulations showed that the two effects can have significant influence to the free-floating dynamics. Furthermore, we showed that the extended parameter identification algorithm improves the accuracy of the dynamic model.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126028044","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}

An identified model is required for synthesizing high performance model based controllers.

In this work, system identification of AMB is approached within the context of commissioning. A procedure for identification is developed and applied to experimental data from a prototype AMB system.
