Design of Minimal Output Samples based Linear Dynamical Functional Observer

This paper proposes a new method of designing a minimal output samples based scalar dynamical functional observer for linear-time invariant systems. This method utilizes the single-rate functional observer design [1] and multirate sampling of the plant output [2]. In addition, a new multirate model has been introduced, which allows further reduction in the order of functional observer proposed in [3]. A method for selecting the number of output samples is also given. A numerical example is provided to illustrate the idea.
