In the design procedure performed on the PM disc motor, genetic algorithm, as an optimisation tool is used. The application of the permanent magnet disc motor is in electric vehicle and therefore it is essential the weight of the motor to be as minimal as possible.

The resonating microstrip structure consists of multiple smaller patches interconnected by varactors. Four groups of varactors biased by four independent bias voltages allow independent control of antenna resonant frequency and polarization state while maintaining good impedance matching. The antenna design does not include any critical “via” connections to the microstrip ground layer, which could aggravate the fabrication process. The proposed design was verified on prototype fabricated for the L-band frequency range. The obtained frequency-tuning range was up to 50% of the central frequency (890 MHz to 1500 MHz) with return loss better than −15 dB within the whole range. The polarization could be adjusted either linear in an arbitrary direction or circular (left- or right-hand) with 180° phase-reversal option.","PeriodicalId":256285,"journal":{"name":"IEEE EUROCON 2009","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121614535","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, due to some effects such as fading or shadowing, an individual sensor may not be able to reliably detect the existence of a Primary User (PU). Cooperative spectrum sensing that is proposed to solve such problem, uses a distributed detection system to overcome the severe decadent of received signal strength at some locations in the network. This paper considers the performance of a distributed Neyman-Pearson (N-P) detection system consisting of N sensors and a fusion center, in which the decision rules of the sensors have been given and the decisions of different sensors are mutually independent conditioned on both hypotheses. Theoretical analysis on the performance of this fusion center is carried out. We obtain the conditions for the fusion center to achieve an overall probability of detection that is greater than the local probability of detection of each sensor. Numerical results show that the AND, OR and Majority decision fusion rules are the special cases of the N-P fusion rule.","PeriodicalId":256285,"journal":{"name":"IEEE EUROCON 2009","volume":"2017 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121617085","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 annual peak load and minimum load recorded at the site is 130 kW and 28 kW, respectively. A 50-kW wind turbine is selected to demonstrate the economic feasibility of the turbine as a fuel saver. The results show that wind energy utilization is an attractive option with total specific cost of the selected wind turbine at 7.8 ¢/kWh at 7.55% discount rate comparing to diesel generation operating cost of 14.3 ¢/kWh, considering the capital cost of diesel units as sunk.

Since, the VSC has several attractive advantages such as high speed response, good transient performance, insensitivity to variation system parameters and external disturbances, simplicity of realization and robustness in nonlinear systems control. A sliding mode controller incorporating fuzzy control helps in achieving reduced chattering, simple rule base, and robustness against load disturbance and nonlinearities. The simulation of nonlinear model SRM using the proposed technique is carried out and the results are compared with those obtained using the conventional PI controller. Also, the experimental setup is verified, which consists of building IGBT inverter H-bridge and associative drive gate with its control circuit and interfacing between control algorithm and experimental hardware. Both simulation and experimental results with the proposed algorithm show that, the system performance is improved significantly in the presence of load disturbance and is insensitive to some parameters variations of the system. Also, the variable structur technique is used to improve the stability requirements of the dynamic system when all the Lyapunove stability condition are realized.","PeriodicalId":256285,"journal":{"name":"IEEE EUROCON 2009","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133921608","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}
