The conventional proportional derivative (PD) control algorithm with appropriate gain scheduling is generally applied to a dynamic positioning (DP) system. However, finding gains through makes the DP system more complicated. A sliding-mode controls an arbitrary point, such as turret on floating production storage and offloading (FPSO) vessel. This was developed for can be FPSO vessels consideri...

A hybrid method is proposed for optimizing rigid tapping parameters and reducing synchronization errors in Computer Numerical Control (CNC) machines. The integrates uniform design (UD), regression analysis, Taguchi method, fractional-order particle swarm optimizer (FPSO) to optimize parameters. Rigid were laid out a 28-level layout the experiments this study. Since UD provided with dispersion e...

Accurate modeling and parameters identification of Metal Oxide Surge Arrester (MOSA) are very important for arrester allocation, systems reliability and insulation coordination studies. Several models with acceptable accuracy have been proposed to describe this behavior. It should be mentioned that the estimation of nonlinear elements of MOSAs is very important for all models. In this paper, a ...

In the present work, the open source Computational Fluid Dynamics (CFD) packageOpen Field Operation and Manipulation (OpenFoam®) is used to simulate wave-structure interactions and a new wave boundary condition is developed for extreme waves. The new wave boundary condition is implemented for simulation of interaction with a fixed/floating truncated cylinder and a simplified Floating Production...

Nowadays, the floating production storage and offload system (FPSO) is one of most common platform types for offshore oil production. The traditional arrangement stiffened panels creates obstacles automated cleaning inspections by remote devices. This paper summarizes results an initial study design construction FPSO hulls with SPS in order to overcome this problem. main goal have walls bottom ...

This paper mainly discusses the demand bidding and risk management of user aggregators by considering profit risk. The covariance matrix price was used to analyze model under an uncertain price. By revenue cost, strategy derived obtain maximum profit. using a risk-tolerance parameter β, new for that takes both into consideration formulated. We simulated posed fluctuating prices this model. Fina...

The Dynamic Economic Load Dispatch (DELD) is the major problem in power system operation and control. The main objective of DELD is to minimize the total fuel cost of the generators while satisfying all the operating constraints. Premature convergence is the major problem of DELD in large power system. Conventional methods took long time to converge the DELD. To handle the DELD problem, an effi...

Associative neural memories are models of biological phenomena that allow for the storage of pattern associations and the retrieval of the desired output pattern upon presentation of a possibly noisy or incomplete version of an input pattern. In this paper, we introduce fuzzy swarm particle optimization technique for convergence of associative neural memories based on fuzzy set theory. An FPSO ...
