英文摘要: This project investigates force control and virtual prototype simulation of the terminal restricted wheeled mobile manipulators. Research of force control and virtual prototype simulation about this kind of systems has a wide range of mechanics and control engineering background. The research includes the following aspects: 1. In the case of the terminal constraint surface being known, we mainly investigate robust force control of the mobile manipulators with parameters and dynamic uncertainty by dynamic feedback control, and adaptive force control of the mobile manipulators with unknown parameters based on logic-based switching. 2. In the case of the terminal constraint surface being unknown, we mainly investigate online intelligent prediction algorithm about curvature and stiffness of the unknown terminal constraint surface, and robust/adaptive force control based on intelligent prediction. 3. Design force control virtual prototype simulation platform for the terminal restricted mobile manipulators, and then verify effectiveness of proposed control algorithms through virtual prototype simulations. The research of this project will enrich and expand control technology of mobile manipulators and control theory of nonholonomic system, and offer basic technology for the further experimental study.
