Stability Analysis of Roadway Groups under Multi-Mining Disturbances

Mining and Analysis of Traffic Safety and Roadway Condition Data

Decision makers working to improve transportation systems must constantly balance the need to improve roadway safety through infrastructure investment with constraints of available resources. We have explored the additional information available to transportation decision makers by integrating two independent datasets, traffic accident and roadway pavement condition data. The roadway condition ...

Stability Analysis of Multi-Fingered Grasp under Destabilizing Gravity Effect

In this paper, we deal with the stability analysis of an object grasped by fingers with linear stiffness in the case where the gravity effect is considered. The stability of the grasp is defined based on the potential energy of the grasp. The analysis problem is formulated as finding a condition of the stiffness parameters and contact points for the position of the center of gravity (COG) to ex...

Nonlinear L 2 - stability under large disturbances 1

We derive time-asymptotic decay rates in L for large disturbances to some important classes of solutions of the Cauchy problem for a number of uniformly parabolic equations, provided only that the disturbances belong to appropriate L spaces at initial time. Examples considered include the scalar nonlinear advection–di usion equation ut + f(u)x =(b(u)ux)x and the parabolic system ut + (u’(|u|))x...

New Discrete Sliding Mode Control for Nonlinear Multivariable Systems: Multi-Periodic Disturbances Rejection and Stability Analysis

The Sliding Mode Control (SMC) is well known by its robustness to parameter uncertainties or external disturbances. The repetitive control (RC) is able to track or reject periodic and multi-periodic signals. This paper presents a new control strategy as a combination of a Sliding Mode approach and Repetitive Control to reject periodic and multi-periodic disturbances in the case of nonlinear mul...
