Observer design for a class of linear time-varying systems

The problem of observer design for a class of linear time-varying system is researched in this paper. An augmented linear time-varying system is proposed to extent the application of the previous results. Moreover, using the observable block companion form of the augmented linear time-varying system, this paper presents an algorithm of observer design. Compared with other observer design approaches, the prominent feature of the algorithm is that of simplifying the computational complexity. Finally, simulations are designed in linear time-varying system and results are presented to demonstrate validity of the proposed algorithm.
