Wheelchair ergometers are a highly valuable tool in the study of the biomechanics of manual wheelchair propulsion. However, current ergometers have some drawbacks that affect their level of realism. For example, the moment of inertia of the wheelchair-user system and the caster wheels' orientation are usually neglected, despite their high influence on the wheelchair's behavior. Taking these factor... View full abstract»

A reset disturbance compensation scheme is developed to reject midfrequency narrowband disturbances, with an application to the hard disk drives (HDDs). Generally, disturbance at the midfrequency band is not effective to reject through the feedback control based on the internal-model principle or high gain control due to phase stability. This paper investigates a reset control scheme and its favor... View full abstract»

• ### Reducing Vibration by Digital Filtering and Input Shaping

Publication Year: 2011, Page(s):1410 - 1420
Cited by:  Papers (28)
| |PDF (1131 KB) | HTML

The residual vibration of flexible systems can be reduced by shaping the reference command with notch filters, low-pass filters, and input shapers. Since the introduction of robust input shaping, there has been substantial evidence that input shaping is better than both notch and low-pass filtering for suppressing vibration in mechanical systems. Much of this evidence is empirical comparisons betw... View full abstract»
