To properly maintain and manage track surfaces, the amount of collapsed settlement of a ballast bed must be determined. However, high maintenance costs make it difficult for railway operators to fully maintain and manage track surfaces. Therefore, we propose a method of estimating the shape of the ballast bed using Dense Inverse Search (DIS) optical flow in images captured using a camcorder, which...
This paper considers the robust consensus problem of Lipschitz nonlinear multi-agent systems with matched disturbances and time-delay dynamics. By LMI approach based on Lyapunov function, distributed adaptive protocols are proposed, which rely on the state information of neighbor agents. Theoretical analysis indicates that the proposed protocol achieve both the leaderless and leader-following consensus...
