Abstract
The present invention relates to a mobile system and a moving method of the mobile system. According to the present invention, a natural period is measured from a vibration component signal generated by a force due to acceleration/deceleration of wheels, and the mobile system moves by applying an acceleration profile containing an acceleration period or a deceleration period based on the natural period. Therefore, the acceleration profile based on the natural period is applied such that vibration that is visible to a user is not generated during acceleration and deceleration of the mobile system. As a result, quality of the mobile system is improved.
Claims20
A mobile system having a main body comprising a wheel, the mobile system comprising:
- a natural period measuring unit for measuring a natural period from a vibration component signal generated by an external force or acceleration/deceleration of the wheel;
- and
- a speed profile applying unit for applying a speed profile including an acceleration period or a deceleration period to drive the wheel, the acceleration and deceleration periods being based on the natural period.
A moving method of a mobile system having a main body comprising a wheel, the method comprising:
- a) measuring a natural period from a vibration component signal generated by external force or acceleration/deceleration of the wheel of the mobile system;
- and
- b) moving by applying a speed profile containing an acceleration period and a deceleration period based on the natural period.
