| 总结: | This paper introduces the modeling and control design of a two-wheeled wheelchair
(TWW) based on structure-preserving port-Hamiltonian concept. In this paper, a model of
TWW with features, including space-saving, four to two-wheel transformation, and adjustable
seat height is proposed to increased mobility and independence of the user. Then, the
mathematical model of a TWW in its balanced mode is derived. The model is based on the
total energy in the system. The system is divided into subsystems whereby the interconnections
which exist are utilized. The nonlinearity of the model is preserved using port-controlled
Hamiltonian (PCH) system and made to advantage. The proposed controlled is designed based
on the idea of PCH such that the energy balance in the system can be achieved while
stabilizing the system. |
