The application principle of a DC controlled bus over a wide speed range will be firstly detailed. The main idea of such machine topology is that all the active parts are located in the stator so that the air-gap flux can be easily controlled with no need of brushes. This scheme uses a low-cost diode bridge rectifier directly connected to the HEFSPM Generator to transfer active power to the battery and the load. By means of Finite Element Analysis (FEA), a simple methodology was developed to determine the power capability of the proposed structure. The influence of the BH magnetization curve will be also explored. Experimental results on a 3kW - 24-Slot 20-Pole HEFSPM DC Generator were performed and compared to the previous analysis. This relative low time-consuming approach could be useful to predict, with good agreement, the power capability of hybrid excited generator. Finally, an original compensation technique to improve performance of the generator is discussed. An analytical approach to predict the impact of series capacitor on the power capability is proposed and then validated by experiments. It is demonstrated that low speed power capability can be enhanced by 2.5 times using this technique.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"2019 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128056722","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 deployment of these systems in changing uncontrolled environments is one of the main focuses of research in the field of study. The deployment of Reinforcement Learning-based algorithms presents a very promising solution for the modelation of a robotic agents' interaction with its environment. This paper presents an upgrade and an enhancement to the novel approach for the alternative motion control approach for robotic manipulators presented in [1] applied to an exemplar 2DOF robotic manipulator. The enhancement is achieved through a partial decoupling of the manipulators axis. A comparison of its performance with results achieved with a manipulator with fully coupled and one with fully decoupled axis is presented. The introduced hybrid approach provides an excellent compromise between the computational effort linked to the convergency speed of the algorithm and the quality of the gained solutions set by the time needed to complete tasks.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134102336","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}

Controller parameters are determined explicitly as a function of the process parameters and the sampling time of the controller. For developing the proposed theory a generalized single-input single-output stable process model is employed consisting of n-poles, no zeros plus unknown time delay-d. The derivation of the proposed PID control law lies in the principle of the well known Magnitude Optimum criterion. The conventional PID tuning via the Magnitude Optimum criterion is compared with the revised PID control law for several process models met in various industry applications via simulation examples. The revised PID tuning achieves significant improvement of up to 47% reduction of settling time regarding output disturbance rejection and reference tracking even for benchmark processes with long time delay or dominant time constants.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115174314","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 problem is met over many industry applications and involves two basic constraints 1) the existence of a poor process model and 2) inability to measure the states of the process. With respect to these constraints, a systematic method for automatic tuning of the PID controller is proposed. The method is inspired from the well known Magnitude Optimum design criterion. Throughout the investigation, it is shown that the straightforward application of the Magnitude Optimum principle for tuning the PID controller in the ideal case of a known single input-single output linear process model, reveals a feature of the method called `the preservation of the shape of the step and frequency response' of the final closed-loop control system. This shape is characterized by a specific performance in terms of overshoot (4.47%), settling and rise time of the closed-loop control system. For that reason, the proposed method tunes the PID controller's parameters automatically, so that the step response of the control loop achieves the aforementioned specific performance. For applying the method, an open-loop experiment of the process is carried out which serves for initializing the algorithm. The method proceeds by identifying on line the dominant time constants of the plant and the `parasitic' one of the closed-loop system. The potential of the proposed method is justified via simulation examples for two process models met in various industry applications.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115718340","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 paper presents a short primary linear induction motor (LIM) on passive track, where the primary (moving windings) travels between the processing stations. Usually a linear scale is installed along the guidance profile; therefore in case of very long track applications, the costs can be reduced considerably by using a sensorless speed control method. The speed sensorless control should be activated when the vehicle travels outside the processing station, and it uses the classic MRAS (Model Reference Adaptive System) speed and flux estimators based on rotating induction machines. The control strategy during the transition between sensor based and sensorless regions of the track is experimentally verified and discussed.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114345943","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}
