با توجه به اهمیت سیستم های مکانیکی لاگرانژین و کاربرد آن در صنعت در چند دهه اخیر، کنترل این نوع از سیستم ها هموار دغدغه بسیاری از محققین و متخصصین علم کنترل بوده است. در این پایان نامه سعی شده است کنترل کننده pid نامتمرکز مقاوم طراحی شود که بتوان توسط آن به مشخصه های مطلوب کنترلی دست یافت. از آنجا که سیستم های مکانیکی لاگرانژین دارای معادلات دینامیکی غیرخطی می باشند، عمده پژوهش های انجام گرفته ...

Several members of the AGCVIII kinase subfamily, which includes PINOID (PID), PID2, and WAVY ROOT GROWTH (WAG) proteins, have previously been shown to phosphorylate PIN-FORMED (PIN) auxin transporters and control the auxin flow in plants. PID has been proposed as a key component of the phototropin signaling pathway that induces phototropic responses, although the responses were not significantl...

BACKGROUND The impact of Chlamydia trachomatis (chlamydia) control on the incidence of pelvic inflammatory disease (PID) is theoretically limited by the proportion of PID caused by chlamydia. We estimate the population excess fraction (PEF) of treated chlamydia infection on PID at 12-months in settings with widespread chlamydia control (testing and treatment) and compare this to the estimated P...

This paper presents a new optimization algorithm to design an optimal proportional, integral, derivative (PID) controller in hydro-turbine generator governor for damping output frequency oscillations. In this research, we utilize a stochastic and optimal based PID controller to control frequency-response of the hydro turbine. The proposed algorithm is employed to design an optimal PID controlle...

Closed-loop stabilization with guaranteed stability margin using Proportional+Integral+Derivative (PID) controllers is investigated for a class of linear multi-input multioutput plants. A sufficient condition for existence of such PID-controllers is derived. A systematic synthesis procedure to obtain such PID-controllers is presented with numerical examples. Keywords– Simultaneous stabilization...

Adaptive PID controller based on real base function (RBF) network identification by optimal tuning of proportional– integral–derivative (PID) controller parameter is necessary for thematic factory operation of an automatic voltage regulator (AVR) system. This study presents a combined genetic algorithm (GA) and real base function network (RBF) identification control approach to determine the op...

Up to the present time, PID Controller has been widely used to control industrial process loops because of its implementational advantages. However, it is very difficult to achieve an optimal PID gain with no experience, since the parameters of the PID controller has to be manually tuned by trial and error. This paper focuses on tuning of the PID controller using gain/phase margin and immune al...

BACKGROUND Closed-loop (CL) insulin delivery systems utilizing proportional-integral-derivative (PID) controllers have demonstrated susceptibility to late postprandial hypoglycemia because of delays between insulin delivery and blood glucose (BG) response. An insulin feedback (IFB) modification to the PID algorithm has been introduced to mitigate this risk. We examined the effect of IFB on CL B...

Pelvic inflammatory disease (PID) is a clinical syndrome of the female reproductive tract characterized by inflammation of the endometrium, fallopian tubes, or peritoneum (1). PID occurs when microorganisms ascend from the vagina or cervix to the fallopian tubes and other upper genital tract structures (1). PID can result from untreated bacterial infections, including chlamydia and gonorrhea, a...
