摘要:
The transfer function representation of controllers designed by modern state-variable design methods is considered. It is shown that procedures currently being used to design state feedback control laws and state observers (state filters) do not guarantee that the overall controller will be stable. In this paper, additional criteria which do guarantee stable controllers are derived for a general class of second- and third-order systems. A numerical example is presented.
