Noise Tolerance of the Universal Dynamic Controller

S. H. Lam

Abstract

Both the Universal Dynamic Control Law (UDCL)---advocated by this auther---and the classical High Gain Integral Control Law (HGPICL) are robust controllers in the sense that they have ability to approximately honor user-specified control goals without the need of detailed knowledge of the system in question. This paper is a comparative study of these two control laws, showing that the UDCL is substantially superior to the HGPICL in its tolerance of measurement noise. Numerical simulations are presented to support the theoretical conclusions.
