in this paper, we describe our implementation of an interior point algorithm for large scale systems. first we identify system with small and medium methods convex optimization, then we use interior point method for identification. finally we offer an interior point method that uses nonlinear cost function and see that we achieve a good trade-off between error and cpu time. actually, in this pa...
pierre-gerlier forest and his colleagues make a strong argument for the need to expand policy capacity among healthcare actors. in this commentary, i develop an additional argument in support of forest et al view. forest et al rightly point to the need to have embedded policy experts to successfully translate healthcare reform policy into healthcare change. translation of externally generated i...
in this paper, an observer based fuzzy adaptive controller (fac) is designed fora class of large scale systems with non-canonical non-affine nonlinear subsystems. it isassumed that functions of the subsystems and the interactions among subsystems areunknown. by constructing a new class of state observer for each follower, the proposedconsensus control method solves the problem of unmeasured sta...
A power system is a nonlinear one. When turbulence occurs in the power system, the stability of the system depends on the initial operating conditions and the nature of the turbulence. Nowadays renewable energy sources including photovoltaic have a key role to meet high demand of modern societies and to maintain voltage of the buses, while they also provide clean electrical energy. However, inc...
در بررسی های علمی انجام گرفته در زمینه های متفاوتی مثل فیزیک، ادبیات و علوم طبیعی سیستم هایی مشاهده شده است که بررسی آنها دارای پیچیدگی زیادی است و به خاطر این پیچیدگی ها نمیتوان از روشهای سنتی برای فرمولبندی آنها استفاده کرد و باید به دنبال روشهای جدیدی برای تحلیل آنها بود. مکانیک آماری روشهای مناسبی را برای بررسی این سیستمها فراهم میکند. در همین راستا اخیرا تلاشهای زیادی برای مشخص کردن خواص ا...
this paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. an interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...
A Variable Structure Observer Based Control Design for a Class of Large scale MIMO Nonlinear Systems
This paper fully discusses how to design an observer based decentralized fuzzy adaptive controller for a class of large scale multivariable non-canonical nonlinear systems with unknown functions of subsystems’ states. On-line tuning mechanisms to adjust both the parameters of the direct adaptive controller and observer that guarantee the ultimately boundedness of both the tracking error and tha...
مهمترین مسیله در توسعه سیستمهای نرم افزاری مقیاس بزرگ، مبحث معماری آن می باشد. سبکهای معماری نرم افزار، معماران را در ارایه معماریهای خود کمک کرده و باعث انتقال تجربه معماران کارکشته به دیگر معماران می شود.در زمینه معماری نرم افزار، سبک های معماری زیادی ارایه شده است و هر روزه بر تعداد آنها اضافه می گردد و در ارایه سبکهای معماری نرم افزار هیچ محدودیتی وجود ندارند. به همین دلیل برای نظم دادن به ...
reliability evaluation of a large-scale composite power system faces to numerous events/outage and consequently imposes an extensive burden of calculations. in order to simplify the problem, determination of an equivalent system for large-scale power system is inevitable. this paper proposes a framework as reduction technique to separate a composite power system to three areas: external area, o...
