Editorial Pelvic inflammatory disease (PID) is the most important complication of sexually transmitted chlamydial infections, causing major medical, social, and economic problems. PID is an ascending infection, with well over half of the cases caused by Chlamydia trachomatis (CT), Neisseria gonorrhoeae (GC), or both. However, other microorganisms representing abnormal vaginal flora, such as tho...

This article presents the experimental results when comparing the Controllers PID Classic, Nonlinear PID and Fuzzy Gain Scheduling PID used in position controllers, for the tuning of the Classical PID was used the second method

We present a reset control approach to achieve setpoint regulation of motion system with proportional-integral-derivative (PID)-based controller, subject Coulomb friction and velocity-weakening (Stribeck) contribution. While classical PID results in persistent oscillations (hunting), the proposed mechanism induces asymptotic stability significant overshoot reduction. Moreover, robustness an unk...

In this study, trajectory control of the Variable Loaded Servo (VLS) system is performed by using a Fuzzy Logic based Iterative Learning Control (ILC) method. In the study, a Iterative Learning PID (IL-PID) Controller is used as the iterative learning control structure. Also, a fuzzy adjustment mechanism has been added to the control system for specify the initial parameter of the IL-PID contro...

The direct-drive pump control system has been gradually applied to the industrial control field due to its high control precision, fast response, small throttle loss and compact structure. This paper adopts the fuzzy PID control method to resolve the hydraulic cylinder position servo control of direct-drive pump control system. The system model and fuzzy PID control algorithm was established by...

Proportional Integral derivative (PID) controllers are widely used in industrial process control. With its three term functionality providing regulation to both transient and steady state responses, PID control offers the simplest and most efficient solution to many industrial control problems. Tuning of PID gain parameters continuous to be important as these parameters has great influence on t...

ICD-9 codes are conventionally used to identify pelvic inflammatory disease (PID) from administrative data for surveillance purposes. This approach may include non-PID cases. To refine PID case identification among women with ICD-9 codes suggestive of PID, a case-finding algorithm was developed using additional variables. Potential PID cases were identified among women aged 15-44 years at Group...

In chemical process applications, model predictive control (MPC) effectively deals with input and state constraints during transient operations. However, industrial PID controllers directly manipulates the actuators, so they play the key role in small perturbation robustness. This paper considers the problem of augmenting the commonplace PID with the constraint handling and optimization functio...

In power systems, the constant frequency, voltage, and output are desired determine quality of generated electrical energy. Therefore, frequency control is crucial in systems. The parameters conventional controllers used generation plants determined according to system's characteristics at stage installation, they cannot adapt changing system dynamics as lifespan increases. Thus, studies on aut...
