A micromechanical silicon resonant accelerometer (MSRA) is a potential micro accelerometer with high accuracy. One of the most important factors affecting its performance is temperature. To research the effect of temperature on micromechanical silicon resonant accelerometer, this study based on the original micromechanical silicon resonant accelerometer, designs a chip-level temperature-sensitive...
The attraction repulsion (AR) model has been a common mathematical framework to emulate the interactions among mobile agents and to design rigid flocking laws. A main drawback of the AR model is that environment effects are not taken into account in the model. This means that rigid flocking laws can not react to the change of environments. In this paper, we make an attempt to design flocking systems...
It is very important for railway vehicles to have a good braking performance to avoid the phenomenon of idling and skidding, which can be implemented by looking for and keeping an optimal slip ratio. The optimal slip ratio is a value existing in the creep zone of functions between friction coefficient and slip ratio corresponding to the maximum adhesion. Controller based on the sliding mode control...
The high-speed train is typically powered by the catenary wire suspended from poles or towers along the rail. An important issue of the high-speed train's power supply is how to set the precise contact force between the pantograph and catenary wires in real time. It is not a trivial task to investigate the pantograph-catenary contact force regulation in engineering practice since the model of a pantograph...
