Abstract :
This paper is concerned with the design of functional observers for linear time-invariant descriptor systems. The order of these observers is equal to the dimension r of the functional to be estimated. Sufficient conditions for the existence and stability of these observers are given. The obtained results extend those given for the standard systems. Continuous and discrete time systems are considered.
