P^alpha-matrices and Lyapunov scalar stability

چکیده
For partitions of f1; : : : ; ng, the classes of P -matrices are de ned, unifying the classes of the real P -matrices and of the real positive de nite matrices. Lyapunov scalar stability of matrices is de ned and characterized, and it is shown also that every real Lyapunov -scalar stable matrix is a P -matrix. Implication relations between Lyapunov scalar stability and H-stability are discussed.

Further Results on the Stability Analysis for Linear Discrete Time-delay Systems: Lyapunov – Algebraic Approach
In this paper, the problem of stability analysis is investigated for a particular class linear discrete time-delay systems .The criteria are derived by Lyapunov’s direct method using minimization with respect to a scalar parameter and they are expressed by norm and eigenvalue of appropriate matrices. The derived results present new delay independent stability conditions for linear discrete time...
متن کاملGlobal Stabilization of Attitude Dynamics: SDRE-based Control Laws
The State-Dependant Riccati Equation method has been frequently used to design suboptimal controllers applied to nonlinear dynamic systems. Different methods for local stability analysis of SDRE controlled systems of order greater than two such as the attitude dynamics of a general rigid body have been extended in literature; however, it is still difficult to show global stability properties of...
متن کاملRobust stability of fuzzy Markov type Cohen-Grossberg neural networks by delay decomposition approach
In this paper, we investigate the delay-dependent robust stability of fuzzy Cohen-Grossberg neural networks with Markovian jumping parameter and mixed time varying delays by delay decomposition method. A new Lyapunov-Krasovskii functional (LKF) is constructed by nonuniformly dividing discrete delay interval into multiple subinterval, and choosing proper functionals with different weighting matr...
متن کاملConservatism-free Robust Stability Check of Fractional-order Interval Linear Systems
This paper addresses a necessary and sufficient robust stability condition of fractional-order interval linear time invariant systems. The state matrix A is considered as a parametric interval uncertain matrix and fractional commensurate order is considered belonging to 1 ≤ α < 2. Using the existence condition of Hermitian matrix P = P ∗ for a complex Lyapunov inequality, we show that a fractio...
متن کاملLyapunow Stability, Semistability, and Asymptotic Stability of Matrix Second-Order Systems
Necessary and sufficient conditions for Lyapunov stability, semistability and asymptotic stability of matrix second-order systems are given in terms of the coefficient matrices. Necessary and sufficient conditions for Lyapunov stability and instability in the absence of viscous damping are also given. These are used to derive several known stability and instability criteria as well as a few new...
