The non-standard dynamics characteristics of hypersonic vehicles, the aerodynamic effects together with the wide range of speed and altitude during operation make modeling and control of these vehicles highly challenging. Modeling and analysis of hypersonic vehicles are important for control and navigation system design. A six degrees of freedom simulation model of the wing cone generic hypersonic...
The BTT flight control system design is researched and established for flight vehicle control mathematical model, control gain solution and mathematical simulation. Firstly, the design of BTT flight control system is put forward, and then a linear controller is designed with fuzzy control theory. Secondly, the flight vehicle's characteristic is analyzed, and the disturbance model is set up. The Frequency-domain...
Electric Power Steering (EPS) systems have many merits over traditional hydraulic power steering systems in fuel economy, variable assist capabilities and favorable road feeling by virtue of adjustment assist characteristic with adopting assist motor in replacement of hydraulic pump. This paper aims at modeling the mechanical parts, the assist motor and electronic control unit by bond graph technique...
Locomotion systems of wheeled mobile robots and electric cars consist of a rectangular or a circular platform, one or two drive wheels and one or two free wheels (when a unicycle type robot has only one drive wheel). The wheels may be fixed, steering, castor or Swedish. The steering wheel has a rotation about the vertical axle, passing through the center of the wheels. The castor wheel's vertical...
