Families of regimes for control systems are studied possessing the so called quasi–control-lability property that is similar to the Kalman control lability property. A new approach is proposed to estimate the degree of transients overshooting in quasi–controllable systems. This approach is conceptually related with the principle of bounded regimes absence in the absolute stability problem. Its ...

A bstract We explore a simple but extremely predictive extension of the scotogenic model. promote symmetry ? 2 to flavour non-Abelian ?(81), which can also automatically protect dark matter stability. In addition, ?(81) leads striking predictions in lepton sector: only Inverted Ordering is realised, absolute neutrino mass scale predicted be m lightest ? 7 . 5 × 10 ? 4 eV and Majorana phases are...

For the nano piezoactuator with hysteresis in control system its set of equilibrium positions is segment line. By applying Yakubovich criterion for condition absolute stability evaluated.

Stability analysis in compliant mechanism (CM) design is of utmost importance. From a practical point of view, a CM that is unstable is of no significance (has no practical value). Three useful plots were considered in the evaluation of each of the dynamic models of nine configurations of compliant constant-force compression mechanisms (CCFCMs) for their stability characteristics, which include...

Abslraet-Recent applications of absolute stability methods to robustness analysis have led to a rebirth of interest in this topic. This paper is concerned with the robust stability of feedback distributed parameter systems against nonlinear and random disturbances. Our analysis is based on the Lyapunov direct method. To derive a stochastic Lyapunov function, we introduce the special stochastic ...
