| 英文摘要 | In this paper, we develop a technique for constructing the robust D-partition of the m-dimensional controller parameter space X. First, we show that, using Orlando’s formula, the robust D-partition border B that reflects the imaginary axis of the complex s-plane axis is included in the set S = {x l: n – 1(x, q) = 0 q Q}, where Q is a compact m-dimensional uncertain parameter domain, and n – 1 is the (n-1)th Hurwitz determinant of the parametric characteristic polynomial p(s; x, q) of the system. Then, based on the general theorem on the structure of the boundary of the image of a set under nonlinear mappings, we derive an analytical characterization of the boundary of the set S = {x: (x, q) = 0 q Q}, where (x, q) represents n – 1(x, q), p(0; x, q) ,or the leading coefficient of p(s; x, q). Such an analytical characterization of S, the boundary of S, provides a vehicle for constructing the boundary of the robust D-partition border B. As an illustration, the robust D-partition technique is applied to determine the entire set of output (or state) feedback gains, which allows robust stabilization of a linear system under parameter perturbations in prescribed intervals. |
