spring-mass hopper suggests control strategy
2015/8/25
This paper investigates the control of running gaits in the context of a spring loaded inverted
pendulum model in three dimensions. Specifically, it determines the minimal number of steps
required f...
Robust stability of a linear multivariable system, in the sense of robustness under multiplicative transfer function perturbation, is necessarily preserved under sufficiently small perturbations in th...
Structured and simultaneous Lyapunov functions for system stability problems
Lyapunov function system robustness quadratic lyapunov function the numerical values
2015/8/13
It is shown that many system stability and robustness problems can be reduced to the question of when there is a quadratic Lyapunov function of a certain structure which establishes stability of dx/dt...
A branch and bound methodology for matrix polytope stability problems arising in power systems
Robust matrix of power system the linearized dynamics linear system model robust stability
2015/8/12
This paper proposes a formulation to provide necessary and sufficient conditions for robust stability of a family of matrices modeling linearized power system dynamics. A construction for transforming...
Stability robustness of linear systems to real parametric perturbations
Robust parameter linear system the parameter singular value value
2015/8/12
We consider linear time-invariant systems subject to real, parametric variations. The problem of computing the half-sidelength 1/mu_infinity of the largest stability hypercube in the parameter space i...

2015/8/12
For linear systems with unspecified parameters that lie between given upper and lower bounds, we present a branch and bound algorithm that computes the minimum stability degree.

2015/8/12
We consider linear systems with unspecified parameters that lie between given upper and lower bounds. Except for a few special cases, the computation of many quantities of interest for such systems ca...
Synthesizing stability regions for systems with saturating actuators
Controller system control literature
2015/8/11
This paper presents a method of synthesizing controllers for systems with input saturation that guarantees state space regions of attraction. While the computation of stability regions and the corresp...
Influence of Mucilage Viscosity On The Globule Structure And Stability Of Certain Starch Emulsions
Globule structure Mucilage viscosity Stability Starch emulsions
2015/7/31
A study was carried out to determine the influence of mucilage viscosity on the globule structure (i.e. size and number) of certain starch emulsions. The starches investigated were cassava, potato and...
We analyze the refocusing properties of time reversed waves that propagate in two different media during the forward and backward stages of a time-reversal experiment. We consider two regimes of wave ...
We study the qualitative properties of the generalized transition fronts for the reactiondiffusion equations with the spatially inhomogeneous nonlinearity of the ignition type. We show that transition...
Lake in a Bottle:A Laboratory Demonstration of the Unusual Stability Properties of Freshwater
Lake in a Bottle Unusual Stability Properties Freshwater
2015/7/13
Using simple laboratory gear, students can simulate the stratification properties of a freshwater lake and the impact of salt on the relationship between temperature and density. Because some students...
Continuum deformation and stability analyses of a steep hillside slope under rainfall infiltration
Coupled formulation Rainfall infiltration Slope stability Stabilized finite elements Unsaturated soil
2015/7/1
Rainfall weakens an earth slope in a number of ways. It increases the degree of saturation of the soil, thereby breaking the bonds created by surface tension between the soil particles. When the volum...
Stability and consistency of nonhydrostatic free-surface models using the semi-implicit

2015/6/30
The -method is a popular semi-implicit finite-difference method for simulating free-surface flows. Problem stiffness, arising because of the presence of both fast and slow timescale processes, is eas...
