... on a path described by an equation of varying complexity. We examine the effect that the selection of the path has on the size of the deflection regime where negative stiffness is achieved. The stability properties of the equilibrium positions of the system are also investigated, highlighting the influence...

...XinJiang Lu; Han-Xiong Li In real-world applications, a nominal model is often used to approximate the design of an industrial system. This approximation could make the traditional design method less effective due to the existence of model uncertainty. In this paper, a novel stability-based...

... convergence hierarchical systems large-scale systems linear programming stability Design optimization of complex systems often requires multidisciplinary analyses involving significant interactions. Such problems may be solved with an all-in-one (AIO) method in which the system is treated...

...XinJiang Lu; Han-Xiong Li A novel integrated approach is developed to design systems for stability and robustness. First, design parameters with large variation bounds are chosen to maintain system stability. Then, a robust eigenvalue design problem is considered to make the dynamic response less...

To solve this problem, Baumgarte proposed a constraint stabilization method in which a position and velocity terms were added in the second derivative of the constraint equation. The disadvantage of this method is that there is no reliable method for selecting...
