A new data-analysis method is proposed for processing time-force data obtained from a recently developed novel tuning-fork test that has been utilized in hydrogen embrittlement studies. The analysis based on the application of suitable functions are shown to provide good fit data. fitted allow calculation first- and second-order time derivatives initially scattered negative peaks can be associa...

this paper presents a self-tuning pid (proportional and integral and derivative) controller for regulating terminal voltage synchronous generators. in order to modify the system reponse and to overcome the difficulties of self tuning controllers, a dual rate sampling control system was used. system results demonstrated usfulness of the proposed regulator. the designed controller is simple and c...

An important aspect of machine learning (ML) involves controlling the process for ML method in question to maximize its performance. Hyperparameter tuning (HPT) selecting suitable parameters that control process. Given HPT can be conceptualized as a black box optimization problem subject stochasticity, simulation (SO) methods appear well suited this purpose. Therefore, we conceptualize discrete...

The main objective of this work was to develop a tuning method for PID controllers suitable use in an industrial environment. Therefore, computationally simple is presented based on experiment the process without requiring any input from user. Essentially, matches closed-loop response obtained steady-state change experiment. proposed requires no prior knowledge and, its basic form, only measure...

The aim of this study was to present a relay shifting method for feedback identification dynamical systems suitable PID controller tuning. proposed technique uses biased determine frequency response points from single experiment without any assumptions about model transfer function. is applicable open-loop stable, unstable, and integration processes, even with delay, regardless whether they are...

In the most described maximum power point tracking (MPPT) methods in the literatures, the optimal operation point of the photovoltaic (PV) systems is estimated by linear approximations. However, these approximations can lead to less optimal operating conditions and significantly reduce the performances of the PV systems. This paper proposes a new approach to determine the maximum power point (M...

designing of a pid controller is a very common method for industrial process control and due to its very simple and efficient function; it is used in a wide variety of industrial applications. pid controller to reduce the steady state error and dynamic response of the system is used. pid controller design is an inevitable problem in setting the coefficients need to try a lot of trial and error,...
