Abstract :
The new type of integral proportional (IP) observers for descriptor linear systems is proposed. Based on a parametric solution to a type of matrix equations, a parametric approach for the design of the IP observers is established. The proposed approach guarantees the regularity of the observer systems, and gives parameterizations of all observer gains in terms of some free parameters.
