Abstract :
Based on the parametric solutions of a class of Sylvester matrix equation, this paper presents the parametric expressions of all the gain matrices in the finite time functional observers, in which the free parameters can be further utilized to satisfy some specified performance indexes. A numerical example and its simulation results show the simplicity and effectiveness of the proposed parametric design method of finite time functional observers for the linear control systems.
