Impulsive functional observers for linear systems
International Journal of Control, Automation and Systems, 2011The impulsive functional observer design problem for linear systems is addressed. Piecewise differentiable Lyapunov functions are introduced to analyze the stability of the error dynamics. Sufficient conditions for the existence of the impulsive functional observers that are capable of exponentially estimating any given function of the state vector are

Prescribed-Time Observers for Linear Systems in Observer Canonical Form
IEEE Transactions on Automatic Control, 2019For linear systems in the observer canonical form, we introduce a state observer with time-varying gains that tend to infinity as time approaches a prescribed convergence time.

Positive linear observers for positive linear systems
1999 European Control Conference (ECC), 1999A positive linear system is a linear system in which state variables, control and measurements are always nonnegative. In many systems of practical importance, all the state variables are not available for measurements, although the entire state vector has to be known for control strategies for example.

Observability and observers for non-linear systems
1986 25th IEEE Conference on Decision and Control, 1986In this article we propose an observer for minimal bilinear systems. We are examining the cases where we can use this observer for non-linear systems in a more general situation. For this purpose we are proposing the procedure of canonical immersion of a non-linear system in a bilinear one and we solve this problem for the simplest case (dimension for ...

Interval observers for linear systems with delay
Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009This paper focuses on the analysis of some classes of observers for linear systems with a point-wise delay. First, it is pointed out that, classical interval observers for systems without delays are not robust with respect to the presence of delays that appear in a specific structure location, no matter how small it is.

Positive Linear Observers for Linear Compartmental Systems
SIAM Journal on Control and Optimization, 1998The author considers finite-dimensional linear systems such that for all nonnegative initial conditions the following is true: whatever the controls are, as long as they are nonnegative the state and the output remain nonnegative. The basic question addressed in this paper is to give necessary and sufficient conditions such that there is a linear ...

Insensitive observers for discrete time linear systems
Automatica, 1978Abstract The problem of designing an observer insensitive to the variation of system parameters is considered. A K-insensitive observer is defined as an observer that can reconstruct a linear function of the system state in spite of the variation of system parameters, provided the initial state of the observer is suitably chosen.

Sliding mode observer for Switched Linear Systems
2011 IEEE International Conference on Automation Science and Engineering, 2011This work is concerned with the design of an observer for Switched Linear Systems (SLS) subject to an unknown switching signal. The convergence of the proposed SLS observer is proved, based on observability results for SLS, for the following two cases.
