This paper presents and discusses a simulation method for analyzing and evaluating system performance on a rail line from the perspective of speed profile. Dynamic analysis for train motions is introduced, and a discrete time-operation graph is proposed to represent the relation between speed profile and energy consumption. Based on them, an analytical model is formulated to provide a quick insight...
As a key component for underwater gliders, the buoyancy engine plays an important role in the operation of gliders, the performance of which directly affects the monolithic reliability. In this paper, to lower costs of research on the buoyancy engine, a dynamic simulation is established by AMEsim software, in which the performance of the low-pressure boost gear pump and that of the high-pressure hydraulic...
The linear quadratic regulator for the underwater glider is designed, and the motion path of the feedback control system in ocean vertical plane is studied. First, changes of the trajectory path when the glider is in steady moving are tested in this paper. Then, according to the fact that the glider needs sharp turning, two kinds of control strategies are studied. From the contrastive analysis, we...
