This paper proposes a stand-alone photovoltaic (PV) system based on a DC-DC positive output super lift Luo (POSLL) converter. A conventional sliding mode control, a sliding mode controller using a simple sign function and a linear controller using proportional integrator (PI) are used for the control of the PV panel voltage and POSLL converter inductor current and these methods are compared tog...
The board of directors is the head of the supervisor and controller in the organization's system. Since the emergence of widespread changes in the business environment has led organizations to take advantage of diverse specializations and skills, changing the composition of the board and the diversity of vision and perceptual skills in their composition has doubled.One of the indicators o...
An enterprise operating in the mining industry sector is constantly influenced by external and internal enviromental factors, and changes of these factors may increase the risks to its performance. Trying to decrease the risks to a reasonable minimal level, there appears also a demand to establish some changes in the internal control system – to refuse some irrelevant and inefficient control pr...
Introduction & Objective: Multiple sclerosis (MS) is an autoimmune disease with unknown cause. MS is one of the disabling neurologic diseases in adult especially young range that myelin part of central nervous system (CNS) is destructed. The aim of this study was assessment of types A and B personality and internal and external locus of control in multiple sclerosis (MS) patients and comparis...
Today, programs related to "Control of Pharmaceuticals Supply Chain" have become essential and severe punishment has been anticipated to protect these programs. The experience of industrialized countries and leading countries in the field of medicine suggests that the "optimal supply chain control system" is a system based on intelligent logistic design and control so that the transparency of a...
Purpose of this paper is designing of a positional angle control system for a DC servomechanism. The servomechanism system consists of a direct current (DC) motor, a motor driver, a measuring sensor, and a control board to adjust angular position. The motor in the servomechanism has a non-linear element called dead-zone. Presence of dead-zone causes the nonlinear behavior of system. Injecting a...
