Global Stabilizability and Observability imply Semi-global Stabilizability by Output Feedback
We show that smooth global (or even semi-global) stabilizability and uniform complete observability are su cient properties to guarantee semi-global stabilizability by dynamic output feedback for continuous-time nonlinear systems.
متن کاملSingle Output Dependent Quadratic Observability Normal Form
In this paper, two quadratic observability normal forms dependent on output respectively correspondent to drift dominant term and forced dominant term are firstly discussed. Moreover characteristic numbers are studied in order to simplify the calculation of these two normal forms.
متن کاملMulti-Output Dependent Observability Normal Form
This article gives the sufficient condition which guarantees the existence of a reference frame in which a multi-output nonlinear system is linearizable with a linear part depending on its outputs. Our method is based on the design of a reference frame associated with nonlinear observable systems. Moreover, we give the generalization of the result obtained in [5] and [19]. And some examples are...
متن کاملFormulae relating controllability, observability, and co-observability
We present formulae relating controllability, observability, and co-observability arising in the context of supervisory control of discrete event systems. Given a discrete event plant G with event set Σ, uncontrollable event set Σui, and observation mask Mi of the ith supervisor, we first show that the infimal prefix-closed, (L(G), ⋂ i Σui)controllable, and (L(G),Σui,Mi)–co-observable superlang...
متن کاملSingle Output-Dependent Observability Normal Form
This paper gives the sufficient and necessary conditions which guarantee the existence of a diffeomorphism in order to transform a nonlinear system without inputs into a canonical normal form depending on its output. Moreover we extend our results to a class of systems with inputs.
