this paper presents a new strategy based on multi-stage fuzzy (msf) pid controller based on artificial bee colony (abc) for damping power system stabilizer (pss) in multi-machine environment. the recent studies in artificial intelligence demonstrated that the abc optimization is strong intelligent method in complicated stability problems. also, finding the parameters of pid controller in power ...

The paper presents an application of fuzzy logic controller (FLC) with hierarchically structured rule base for a two-link direct drive Celestron telescope. The hierarchical fuzzy logic controller (HFLC) is implemented, as nonlinear blocks used in a control system, for supervision of PID controller for position tracking of the telescope driven by electric motors. The HFLC is composed of two FLC ...

This paper presents an online two-stage Q-learning based multi-agent (MA) controller for load frequency control (LFC) in an interconnected multi-area multi-source power system integrated with distributed energy resources (DERs). The proposed control strategy consists of two stages. The first stage is employed a PID controller which its parameters are designed using sine cosine optimization (SCO...

Degradation of reliability caused by plasma induced damage (PID) has 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. In bulk, PID is relieved by connecting an antenna to a drain because electric charge flow to a substrate. The difference of initial frequencies is 0.79 % between ...

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...

pelvic inflammatory disease (pid) is a rare complication of transvaginal oocyte retrieval. it may result in failure of assisted reproductive techniques (art). during a 7 years period, 5958 transvaginal ultrasound-guided oocyte retrievals resulted in 10 cases of acute pid. eight out of 10 patients were diagnosed infertile because of endometriosis. two patients had mild ovarian, 3 had stage iii, ...

In this paper, a chattering free sliding mode control (SMC) for a robot manipulator including PID part with a fuzzy tunable gain is designed. The main idea is that the robustness property of SMC and good response characteristics of PID are combined with fuzzy tuning gain approach to achieve more acceptable performance. For this purpose, in the first stage, a PID sliding surface is considered su...

An unsolved ancient problem in position control of robot manipulators is to find a stability analysis that proves global asymptotic stability of the classical PID control in closed loop with robot manipulators. The practical evidence suggests that in fact the classical PID in industrial robots is a global regulator. The main goal of the present paper is theoreticall...

This paper presents a practical implementation for a new formula of nonlinear PID (NPID) control. The purpose of the controller is to accurately trace a preselected position reference of one stage servomechanism system. The possibility of developing a transfer function model for experimental setup is elusive because of the lack of system data. So, the identified model has been developed via gat...

A two-stage PID algorithm is proposed with focus on fulfilling some important general requirements such as settling time, overshoot, size of control signal, disturbance rejection and robustness. The proposed method has two main goals. The first is to create an automatic PID computing algorithm giving decent results for a great variety of systems with different design requirements and different ...
