Observability and detectability of singular linear systems with unknown inputs
In this paper the strong observability and strong detectability of a general class of singular linear systems with unknown inputs are tackled. The case when the matrix pencil is non-regular is comprised (i.e., more than one solution for the differential equation is allowed). It is shown that, under suitable assumptions, the original problem can be studied by means of a regular (non-singular) li...

متن کاملObservability analysis and sensor location study for structured linear systems in descriptor form with unknown inputs
This paper deals with the state and input right-hand side observability and the sensor location problem to ensure this property for structured linear systems in descriptor form. The proposed method is based on a graph-theoretic approach. It is applicable to a large class of descriptor systems including regular and nonregular systems even if they are underdetermined, overdetermined or square. Af...
متن کاملSensor location for discrete mode observability of switching linear systems with unknown inputs
This paper deals with the problem of additional sensor placement in order to recover the discrete mode observability of switching structured linear systems with unknown inputs. Such property is quite important for designing control laws, observers, fault detection and isolation schemes (when the fault occurrence implies a commutation between two modes) and so on. The proposed method, based on a...
متن کاملOn Observability and Detectability of Continuous-time Linear Switching Systems
The notion of observability and detectability for a particular class of hybrid systems, linear continuous-time switching systems, is investigated. We compare some of the definitions of observability previously offered and we analyze their drawbacks. A novel definition of observability is proposed corresponding to the possibility of reconstructing the state of the system from the knowledge of th...
