As wind energy is becoming one of the fastestgrowing renewable energy resources,controlling large-scale wind turbines remains a challenging task due to its system model nonlinearities and high external *** main goal of the current work is to propose an intelligent control of the wind turbine system without the need for model *** this purpose,a novel model-independent nonsingular terminal slidingmode control(MINTSMC)using the basic principles of the ultralocal model(ULM)and combined with the single input interval type-2 fuzzy logic control(SIT2-FLC)is developed for non-linear wind turbine pitch angle *** the suggested control framework,the MINTSMC scheme is designed to regulate the wind turbine speed rotor,and a sliding-mode(SM)observer is adopted to estimate the unknown phenomena of the *** auxiliary SIT2-FLC is added in the model-independent control structure to improve the rotor speed regulation and compensate for the SM observation estimation *** examinations and comparative analyses were made using a real-time softwarein-the-loop(RT-SiL)based on the dSPACE 1202 board to appraise the efficiency and applicability of the suggested modelindependent scheme in a real-time testbed.

Neural Regeneration Research 2010年第12期5卷 901-905页

作者： Seyyed Amirhossein Fazeli Anneh mohammad Gharravi Soraya Ghafari Mehrdad jahanshahi mohammad Jafar Golalipour Department of Embryology and Histology Gorgan University of Medical Sciences Gorgan Iran Department of Anatomy Gorgan University of Medical Sciences Gorgan Iran

BACKGROUND： Urtica dioica extract has been shown to play a protective role in the neurodegeneration associated with diabetes mellitus. OBJECTIVE： To verify the neuroprotective efficacy of nettle extract on pyramidal cell density in the CA3 hippocampal subfield following administration of Urtica dioica extract to young diabetic rats. DESIGN, TIME AND SETTING： A randomized, controlled, neurobiological study was performed at the Department of Histology and Embryology at the Gorgan University of Medical Sciences in Iran from 2006 to 2007. MATERIALS： Urtica dioica leaves were collected from a cultivated plant in the suburb of Gorgan （northem Iran） and taxonomically identified by the Department of Pharmacognosy, Mazandaran University of Medical Sciences. METHODS： A total of 20 male, albino, Wistar rats, aged 6-7 postnatal weeks, were randomly assigned to four groups： normal control, diabetic model, preventive, and treatment, with five rats in each group. Diabetes was induced by intraperitoneal injection of streptozotocin （80 mg/kg） in the diabetic and treatment groups. Rats from the preventive group received a hydroalcoholic extract of Urtica dioica （100 mg/kg per day） during the first 5 days, and then streptozotocin （80 mg/kg） was administered on day 6. One week following the streptozotocin injection, rats in the treatment group were intraperitoneally administered hydroalcoholic extract of Urtica dioica （100 mg/kg per day） for 4 weeks. MAIN OUTCOME MEASURES： Following administration of Urtica dioica extract, the dorsal hippocampal formation of the right cerebral hemispheres was stained with cresyl violet. Area densities of CA3 pyramidal cells were measured. RESULTS： The diabetic, preventive, and treatment groups exhibited reduced cell densities compared with the control group （P 〈 0.05）. Moreover, densities of CA3 pyramidal cells in the treatment group were significantly reduced compared with the diabetic model group （P 〈 0.05）. CONCLUSION： The Urtica dioica extract exhi
