Zero State Detectability, New tests of zero-state detectability are suggested. For instance, it is known that any system that admits a robustly stable full The pair (A, B) is stabilizable Every eigenvector of A ⊤ kernel of B ⊤ corresponding to an eigenvalue with positive or zero real part is not in the (PBH Test) rank([A − λI B]) = n, ∀ λ ∈ C such that Re(λ) ≥ Request PDF | On the Zero-state Detectability and Stability of Switched Dissipative Hamiltonian Systems | Switched Hamiltonian system is a kind of important hybrid system. new solution to the problem of nonlinear dynamical systems stabilization under zero-state-detectability assumption or its analogues is presented. Such a A state x 1 is called reachable at time t 1 if for some finite initial time t 0 there exists an input u (t) that transfers the state x (t) from the origin at t 0 to x 1. Two geometric criteria for the zero-state-detectability of the passive system with a This paper investigates the zero-state detectability/ observability of switched dissipative Hamiltonian systems and proposes several sufficient conditions for the problem. , set of states x ∈ X that you cannot estimate or observer Notice that if x(0) ∈ Null(Ok), and u(k) = 0, Abstract Incremental input/output-to-state stability (i-IOSS) is a popular characterization of detectability for nonlinear systems. It is shown that this property plays a fundamental role in solving of invariant set stabilization problems This paper investigates the zero-state detectability/observability of switched dissipative Hamiltonian systems and proposes several sufficient conditions for the problem. Obtained results The zero-state-detectability is an important concept in study on stabilization of nonlinear system. The proposed solution ensures finite time practical stabilization of the An important task associated with state estimation is that of accurate characterization of the possible (compatible) current states following a (possibly long) observation sequence generated In this paper, we investigate the verification problem of initial-state detectability (I-detectability) and initial-state opacity (I-opacity) in discrete event systems modeled by unambiguous This resource give a little more insight into the consequences and causes of losing observability and/or controllability. In this paper, we propose a new notion of detectability, namely initial-and-final-state detectability (IFD), If and only if the column rank of the observability matrix, defined as O = [ C C A C A 2 ⋮ C A n − 1 ] {\displaystyle {\mathcal {O}}= {\begin {bmatrix}C\\CA\\CA^ {2}\\\vdots \\CA^ {n-1}\end {bmatrix}}} is In this paper, we investigate the verification problem of initial-state detectability (I-detectability) and initial-state opacity (I-opacity) in discrete event systems modeled by unambiguous Question: Do you know any formula or method to check if all unstable states are controllable and observable? Because i cannot find any Can we reconstruct x(0) by knowing y(t) and u(t) over some finite time interval [0, T]? We can use the initial condition to calculate the entire state x(t) by solving the diferential equation ̇x = Ax + Bu, and 1. The notion of control Lyapunov functions (CLF) , originated from relaxed Controls, is newly understood as the characterization of zero-state detectability property, thus the difference between . Using the notion of limiting behaviors of the state, output, and switching signals, the concept of a limiting zeroing-output solution is introduced. The important concepts of detectabi Abstract: This paper investigates the zero-state observability and detectability of switched and hybrid dissipative Hamiltonian systems with infinite number of switching subsystems, and proposes a Detectability is a crucial notion regarding the state estimation problem of real-world systems. This leads to a definition of weak zero Abstract—This paper is concerned with the study of both, local and global, uniform asymptotic stability for switched nonlinear time-varying (NLTV) systems through the detectability of output-maps. Then one concludes from Corollary 7 or 8 that (9)- (19) is globally asymptotically stabilized by uk = -yk, which, Unobservable Subspace Unobservable subspace: null-space of Ok = N(Ok) It is basically the space (i. A system is reachable at time t 1 if The stabilization problem for nonlinear dynamical systems under zero-state-detectability assumption or its analogues is considered. The stabilization problem of passive nonlinear affine in control system with initial condition from bounded set is solved. The proposed solution ensures finite time practical Thus, when combined with the de nition in [4], it makes sense to de ne detectability as the property that states should converge to zero when inputs and outputs are zero, and in general be ultimately This paper employs detectability ideas to decide uniform global asymptotic stability (UGAS) of the trivial solution for a class of switched nonlinear time-varying systems when the trivial New notion of detectability of the zero value set of a storage function is introduced. Obtained results The main contribution of this paper is the extension of the notion of zero-state detectability and the introduction of a new notion of V - detectability which helps to follow the abstract With this aim the notion of reduced limiting control systems for switched NLTV systems whose switchings verify time/state dependent constraints, and the concept of weakly zero-state detectability Moreover, the input/output system is zero-state observable because S - {0}. e.
