In small island areas, people still use fossil fuel vehicles as their mode of transportation. This will cause environmental damage. One solution to this problem is developing the electric bike. study uses a power-assisted bicycle type bicycle, consisting battery, dc motor, motor controller, and throttle motor. From test results, can be used support rider. The that rated power more oversized tha...

This paper compares the energy economy and vertical vibration characteristics of in-wheel drive electric vehicles (IEVs), hydraulic hybrid (IHVs) centralized (CEVs). The dynamic programming (DP) algorithm is used to explore optimal consumption each vehicle. analysis shows that IEV consumes more than CEV due its relatively lower motor efficiency, even with fewer driveline components. IHV much be...

Design of reliable and robust controller for electric vehicle in urban and sub urban areas is very much challenging task due to time varying load torque requirement at the wheel of the vehicle. In this paper indirect field oriented vector control of induction motor, PI speed control with anti-windup scheme and hysteresis current control scheme have been proposed for three phase induction motor ...

INTRODUCTION Two-wheel bike riding can be a goal for children with cerebral palsy (CP) and a means of participating in physical activity. It is possible for some children with CP to ride a two-wheel bike; however, currently far fewer can ride compared with their typically developing peers. Evidence supports training targeted towards goals of the child with CP and their family; yet there is litt...

This paper presents the approach adopted by Surrey Satellite Technology Ltd (SSTL) for development of reaction wheels incorporating commercial components and the accelerated life test / qualification philosophy. The paper focuses on the mechanical development and re-qualification of reaction wheel which has flown successfully on many missions having conducted years of in orbit operation. The sc...

Regenerative braking is the key to achieve efficient use of energy and extend driving range in pure electric vehicles. This study proposes a new predictive control method integrating adaptive cubic exponential prediction dynamic programming address problem recovery during regular process four-wheel The considers characteristics an electro-hydraulic combined system. adopted predict vehicle veloc...

As one of the rotating components in reluctance motor type control rod drive mechanism (CRDM), life scroll wheel is closely related to service CRDM. In addition, prediction remaining useful helps optimize maintenance process This paper proposes a hybrid method predict its when available degradation data are rare and failure threshold cannot be accurately defined. First, particle filtering algor...

This paper presents an adaptive controller for the compensation of state-dependent disturbance with unknown amplitude in a digital servo motor system. The state-dependent disturbance is caused by friction and eccentricity between the wheel axis and the motor driver of a mobile robot servo system. The proposed control scheme guarantees an asymptotical stability for both the velocity and position...
