Considering the longitudinal nonlinear model of a hypersonic vehicle including uncertain disturbances, a nonlinear controller based on backstepping method and dynamic inversion method is proposed for solving the tracking control problem. In order to facilitate the control design, the flight vehicle model is decomposed as velocity subsystem and flight path angle subsystem. The command filter is utilized...
Control of Clutch is important on the development of Automated Mechanical Transmission (AMT). The course of clutch engaged is studied to solve the problem of clutch control. Mathematical model of Clutch work is constructed. The friction work and the jerk degree of clutch are studied. And a simulation software is developed, which can calculate the friction work and the jerk degree. The characteristic...
All kinds of motorized-wheel structures are analyzed. For the unitary motorized wheel, since increasing the unsprung mass of vehicle, it adds adverse effects on the vehicle road holding performance and vehicle comfortableness. To decrease the adverse effect for unsprung mass increasing, a method by attaching the motor in the wheel through springs and dampers of exclusive use is brought out. It is...
A new dynamic coupling device of hybrid electric vehicle (HEV) was put forward based on the traditional symmetric bevel gear differential. And the co-simulation platform was constructed based on AMESim and MATLAB by analysis of the transfer mechanism for the new dynamic coupling. The control strategy was developed using MATLAB, the dynamic model of HEV was built using AMESim, and the data exchange...
