Degradations of reliability caused by plasma induced damage (PID) have become a significant concern with miniaturizing a device size. In this paper, we measure frequencies of ring oscillators with an antenna structure on a single stage. PID is relieved by connecting an antenna to a drain because charge flows to a substrate. The difference of initial frequencies is 0.64 % between structures whic...

This paper presents the comparison of tracking control performance of fuzzy PI Controller with fuzzy PID and conventional PID controllers. Fuzzy PI controller and Fuzzy PID controller composes of Mamdani type fuzzy controllers and parameters are adjusted to meet the desired control system performances both in transient state and steady state. Computer simulations are done for controlling the ti...

با پیشرفت روز افزون صنعت خودروسازی، سیستم های کنترلی جدید به منظور بهبود عملکرد سیستم ایمنی خودرو پیشرفته تر می شوند. یکی از مهم ترین سیستم های ایمنی خودرو، سیستم ترمز ضد قفل (abs) می باشد که در طی چند سال اخیر پیشرفت چشمگیری داشته است. وجود عوامل غیرخطی و نامعینی های وارد بر خودرو در طی فرایند ترمز گیری، یک کنترل کننده غیرخطی مقاوم برای ترمز ضد قفل، امری ضروری می باشد. در این پایان نامه به من...

Polynomial stabilization method has important feature in PID tuning. It computationally characterizes the entire set of admissible PID gains for various control system configurations. This paper shows a correction is needed in order to find all robust PID region controllers that satisfy a given robust performance. We also provides selection procedure for searching the best PID gains controllers...

Industry applications mainly use linear PID algorithms might deliver an insufficient performance dealing with nonlinear operating systems. A fuzzy PID controller results in a nonlinear control surface which can be adjusted to a controlled plant by rule based modification, nonlinear membership function application and inference rule selection. The tuning process is one of the most difficult step...

This paper proposes a novel adaptive genetic algorithm (AGA) for the multi-objective optimization design of a fractional PID controller and applies it to the control of an active magnetic bearing (AMB) system. Different from PID controllers with three constants, the fractional PID controller’s parameters are composed of proportional constant, integral constant, derivative constant, derivative o...

BACKGROUND With the publication of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), an alternative model for personality disorders based on personality dysfunction and pathological personality traits was introduced. The Personality Inventory for DSM-5 (PID-5) is a 220-item self-report inventory designed to assess the personality traits of this model. Recen...

PURPOSE Pelvic inflammatory disease (PID) is a common disorder of the reproductive tract that is frequently misdiagnosed and inadequately treated. PID and its complications, such as infertility, ectopic pregnancy, and chronic pelvic pain, are preventable by screening asymptomatic patients for sexually transmitted infections (STIs) and promptly treating individuals with STIs and PID. RECENT FI...

Pelvic inflammatory disease (PID) and more specifically salpingitis (visually confirmed inflammation) is the primary cause of tubal factor infertility and is an important risk factor for ectopic pregnancy. The risk of these outcomes increases following repeated episodes of PID. We developed a homogenous discrete-time Markov model for the distribution of PID history in the UK. We used a Bayesian...

In this paper, we examine a design method of modified PID (Proportional-IntegralDerivative) controllers for multiple-input/multiple-output plants. PID controller structure is the most widely used one in industrial applications. Recently the parametrization of all stabilizing PID controller has been considered. Yamada and Hagiwara proposed a design method of modified PID controllers such that mo...
