The unified control strategy for planar Acrobot and Pendubot

open access: yesShenzhen Daxue xuebao. Ligong ban, 2023
For the planar Acrobot and Pendubot with passive joints at different positions, a control strategy based on trajectory planning and tracking control is proposed to achieve their unified control. The whole control process is divided into two phases.

Large-deviation analysis for counting statistics in mesoscopic transports [PDF]

open access: yes, 2011
We present an efficient approach, based on a number-conditioned master equation, for large-deviation analysis in mesoscopic transports. Beyond the conventional full-counting-statistics study, the large-deviation approach encodes complete information of ...
