چکیده کنترل برداری پیشرانه مکانیزمی برای تغییر جهت پیشران? موتور در راکت ها یا وسایل پروازی می باشد. این مکانیزم در راکت های سوخت جامد توسط اتصالات انعطاف پذیر در جهت کنترل موقعیت یا سرعت زاویه ای وسیله انجام می شود. در وسایل پروازی سوخت جامد پیشرفته، کنترل برداری پیشرانه به کمک انحراف بردار پیشرانه و با استفاده از سروُ مکانیزم های الکتریکی مانند عملگر الکترومکانیکی انجام می گیرد. در این پروژه،...
Small fluctuations caused by random changes of loads exist continuously in power grids, which are called ambient signals. Using time-synchronized phasor measurements, the closedloop identification of power system based on ambient data is discussed, which can reflect accurate operating conditions currently and provide critical information for system analyzing and controller designing. The closed...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
The purpose of this paper is to improve the modeling of the data-driven wind turbine system that receives data from noise signals. Most of the data on industrial systems is noisely and data noise is inevitable and natural. The method and idea proposed in this paper, Data Fogging, significantly reduce the impact of noise on data-driven wind turbine system modeling, which is the basis of this met...
Evaluation of any communication technology is only relevant in the context of the operating environment. This seemingly obvious point, frequently bypassed in general analysis, cannot be overlooked in the field of power line communications. The conditions required for superposition to be applicable (i.e., linearity and time invariance) are not met for the majority of power line networks. In this...
