multiple sclerosis is a chronic inflammatory disease of central nervous system.women are more susceptible to this disease. one of the obvious clinical complaints in women with multiple sclerosis specially treated with beta interferones is menstrual cycle irregularity. the aim of this study was to determine the prevalence of menstrual irregularities and probable changes in blood levels of relate...

An analysis of on-line autonomous robust tracking controller based on variable structure control is presented for an aerospace launch vehicle. Decentralized sliding-mode controller is designed to achieve the decoupled asymptotic tracking of guidance commands upon plant uncertainties and external disturbances. Development and application of the controller for an aerospace launch vehicle during a...

We propose a torque overlay based robust steering wheel angle control of electric power steering (EPS) for lateral control using backstepping design. The main contribution of this paper is that the proposed method is designed based on torque overlay and that the global uniform ultimate boundedness of the steering wheel angle tracking error is guaranteed using only steering wheel angle feedback ...

The problem of designing an improved nonlinear robust controller is addressed adopting three perspectives for static synchronous compensator (STATCOM) system in the presence of time-delay, uncertainty parameter and external disturbances. At first, in order to reduce high degree coupling between system state variables and estimation errors, uncertain parameter is estimated by using the system im...

In this study, we develop fuzzy adaptive tracking control via two-layer fuzzy observers, variable structure systems (VSS), and H∞ control algorithm for nonlinear systems with plant uncertainties, output delays, and external disturbances. The Takagi–Sugeno fuzzy dynamic model with adaptation capability is used to approximate the nonlinear system. When the system states are not available, the sta...

Throughout the history of technological progress, attempts have been made to build a machine that looks and behaves like humans. This paper presents a semi‐anthropomimetic robot. The robot structure consists of a human‐like upper body mounted on a mobile platform (mobile base, cart). The robot uses the three‐wheeled mobile platform with two driving wheels and on...

The paper considers the problem of output external unknown disturbance compensation under unmeasurable state vector for a class linear systems with control channel delay. It is assumed that an autonomous generator. A special observer was built to estimate disturbance. system extended formed on base observer’s estimates. controller provides proposed. An algorithm disturbances input delay present...

The conditions of asymptotic stability the trivial solution stochastic diffusion dynamic systems automatic regulation with external disturbances are obtained. In work is to find criteria for absolute solutions (SAR) disturbances. problem determining sufficient algebraic SARs aftereffect and taking into account relevant, since its makes it possible study complex using matrix calculations.

The reliability of Bluetooth is discussed from technical point of view with respect of noise immunity and performance under influence of external disturbances. The emphasis is on possible industrial applications of Bluetooth technology.
