This paper addresses an approximation-based anti-windup (AW) control strategy for suppressing the windup effect caused by actuator saturation nonlinearity in proportional–integral–derivative (PID) controlled systems. The effect of actuator constraint is firstly regarded as a disturbance imported to the PID controller. The external disturbance can then be modeled by a linear differential equatio...
Objectives The prevalence of death anxiety in older adults is high. Thus, the aim of the present study was to explore the relationship between coping strategies and locus of control with death anxiety in older adults. Methods & Materials In this descriptive and cross-sectional study, 113 elderly adults older than 60 years were recruited from the city of Tehran via available sampling method. Fo...
Background: Different factors, such as personality and psychological characteristics, are effective in the self-care and control of diabetes. This study aimed at determining the effect of educational intervention based on locus of control structure of attribution theory on the self-care behavior of patients with type II diabetes. Methods: This was a quasi-experi...
The purpose of this study was to compare of hip abductor and external rotator muscles strength between male soccer players with ACl rupture and healthy male soccer players. 30 male participants (15 soccer players with ACL rupture as sample group and 15 healthy soccer players as control group) participated in this study. Hip abductor and external rotator muscles strength tests including nor...
this study investigated the effects of giving information and the role of individual characteristic in level of anxiety in general surgery operation patients. 112 male and female (with a mean age of 31.8) in two groups of experimental and control subjects were studied. the subjects answered to rater internal-external locus of control scale. then the subjects in the experimental group were given...

This paper proposes an adaptive control method based on the feedback linearization technique and a proposed neural network, for tracking and position control of an industrial manipulator. At first, it is assumed that the dynamics of the system are known and the control signal is constructed by the feedback linearization method. Then to eliminate the effects of the uncertainties and external d...
