When operating in this mode, the wind power plant controller is free to distribute power set-points to the individual turbines, as long as the total power demand is met. In this work, we design a controller that exploits this freedom to reduce the fatigue on the turbines in the wind power plant. We show that the controller can be designed in a decentralized manner, such that each wind turbine is equipped with a local low-complexity controller relying only on few measurements and little communication. As a basis for the controller design, a linear wind turbine model is constructed and verified in an operational wind power plant of megawatt turbines. Due to limitations of the wind power plant available for tests, it is not possible to implement the developed controller; instead the final distributed controller is evaluated via simulations using an industrial wind turbine model. The simulations consistently show fatigue reductions in the magnitude of 15-20%.","PeriodicalId":379739,"journal":{"name":"2013 IEEE International Conference on Control Applications (CCA)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115011332","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}

A boost converter is important in LED lighting, photovoltaic systems, hybrid electric vehicles etc. But the presence of a Right Half Plane (RHP) zero in the small-signal model of a boost converter for its continuous current mode operation restricts its speed of response. With standard fixed frequency control, the effect of a RHP zero cannot be eliminated completely. In this paper, the principle of Smith Predictor control is used to minimize the effect of RHP zero and maximize the achievable control loop bandwidth with sufficient phase margin. The Smith Predictor structure is realized with a Sallen-Key band pass filter and simulated with a voltage mode (VM) boost converter and a type III compensator in closed loop. The analytical results are verified with large-signal CADENCE switched simulations. The limitations of Smith Predictor control are also discussed in this context.","PeriodicalId":379739,"journal":{"name":"2013 IEEE International Conference on Control Applications (CCA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115463060","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}

This noise is caused by interaction between magnetic radial forces and mechanical stator structure. Current harmonics may excite stator natural frequencies, thus leading to vibrations responsible for acoustic noise. In this paper, we propose a new method based on control to reduce current harmonics. They are modeled as the consequence of a sinusoidal disturbance at a given frequency. This is estimated by an observer and this estimation is used to cancel harmonic components contained in stator currents.","PeriodicalId":379739,"journal":{"name":"2013 IEEE International Conference on Control Applications (CCA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115695646","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}

They provide significant advantages compared to traditional electromagnetic motors like fast control, high torque, low electromagnetic interference and light weight. It is however difficult to formulate exact mathematical model of the ultrasonic motor due to complex nonlinearities involved as a result of its use of friction and inverse piezoelectric phenomena as its driving mechanism. These nonlinearities pose significant problem for precise position control of the motor. Previous research have therefore suggested developing control design using elaborate nonlinear control schemes like Sliding Mode Control (SMC) used in tandem with advanced machine learning algorithms like genetic algorithms. The drawback of implementing these approaches is the computational cost and complexity involved. In this paper we present a new schema for control of USM. We divide the problem into two complementary parts, namely estimation of the motors parameters and controller design based on the estimator result. Depending on the precision requirement of the application the estimation process can be made nonlinear and /or time varying. Similarly based on the affordable computational complexity, we can choose a linear or a nonlinear controller. Results of experiments conducted show the comparative performance of these different categories. Guidelines are suggested for suitable combination of them depending upon a user's requirement.","PeriodicalId":379739,"journal":{"name":"2013 IEEE International Conference on Control Applications (CCA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116944526","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}

To serve the demands of many applications, often a large number of single battery cells are combined into modules or packs of batteries. However, the determination of state of charge and parameters of the single cells is important for the reliable and safe operation of batteries. In the present paper, we investigate the observability and identifiability of cells in battery packs, realized in parallel and serial connections. The analysis is based on linear and nonlinear observability tests exploiting an equivalent circuit model. This leads to conclusive findings concerning the feasibility of estimating the states of single cells from lumped measurements. As shown for cells in parallel connection, one voltage and one current sensor are sufficient to determine state of charge and model parameters of the individual cells. The results are illustrated by simulations.","PeriodicalId":379739,"journal":{"name":"2013 IEEE International Conference on Control Applications (CCA)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115211879","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}

These high-order models are generally not suitable for control analysis and synthesis. This paper presents a methodology to obtain a reduced-order linear parameter varying (LPV) model from a set of high-order linear time invariant (LTI) models. Firstly, the high-order LTI models are locally approximated using modal and balanced truncation and residualization. Then, an appropriate coordinate transformation is applied to allow interpolation of the model matrices between points on the parameter space. The obtained LPV model is of suitable size for designing modern gain-scheduling controllers based on recently developed LPV control design techniques. Results are thoroughly assessed on a set of industrial wind turbine models generated by the recently developed aeroelastic code HAWCStab2.","PeriodicalId":379739,"journal":{"name":"2013 IEEE International Conference on Control Applications (CCA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116004666","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}
