The paper presents a number of advanced solutions on electric machines and machine-based systems for the powertrain of electric vehicles (EVs). Two types of systems are considered, namely the drive systems designated to the EV propulsion and the power split devices utilized in the popular series-parallel hybrid electric vehicle architecture. After reviewing the main requirements for the electri...

[Purpose] The aims of this study were to identify the relationship between motor recovery and gait velocity during dual tasks in patients with chronic stroke and determine automatic gait ability following stroke. [Subjects and Methods] Thirty-three outpatients and twelve healthy subjects participated in a cross-sectional assessment. Community ambulation was assessed using a self-administered qu...

It is difficult to perform two tasks at the same time. Such performance limitations are exemplified by the psychological refractory period (PRP): when participants make distinct motor responses to two stimuli presented in rapid succession, the response to the second stimulus is increasingly slowed as the time interval between the two stimuli is decreased. This impairment is thought to reflect a...

This study presents a bridge arm attached to the FESS motor’s neutral point and reconstructs mathematical model after phase-loss fault assure safe dependable functioning of motor such fault. To increase tolerance in motors with faults, 3D-SVPWM technology was utilized operate motor. The parameters zero-axis current compensation control were modified based on dual-closed-loop strategy for speed ...

OBJECTIVE To determine whether the impairment of perceptual-motor performance often observed during the initial stages of space flight is attributable to the direct effects of microgravity on sensory-motor input-output relationships or to cognitive overload arising from the variety of stressors encountered in this environment. BACKGROUND Experimental evidence is contradictory, and the present...

Abstract: The simultaneous elimination of common-mode voltage and DC-link capacitor voltage imbalance is achieved in a five-level inverter scheme for an induction motor drive throughout its operating range. A dual five-level inverter-fed open-end-winding induction motor structure is used for the proposed drive. Initially, the operating limitations of achieving this dual task for the fivelevel i...

Background. People with Parkinson’s disease (PD) often fall while multitasking or walking backward, unavoidable activities in daily living. Dual tasks involving cognitive demand during gait and unfamiliar motor skills, such as backward walking, could identify those with fall risk, but dual tasking while walking backward has not been examined in those with PD, those who experience freezing of ga...

In this paper, an innovative control method, namely angle-current dual-loop feedback control, is proposed for use with microstepping motors. This method involves adjusting the stator excitation angle and current simultaneously on basis of sensor motor. The expected to enhance positioning accuracy energy efficiency stepping was tested by implementing it in a motor system, which included core mic...

Introduction: While most symptoms from concussions recover in 7-10 days [1], challenging motor control tasks can be affected longer. Concussed athletes have shown prolonged changes in challenging motor control tasks such as dual-task gait [2], but only traditional stability measures such as medio-lateral (ML) sway have been investigated thus far. The current investigation compared the local dyn...
