Abstract :
The paper presents results on the inclusion principle for uncertain, nominally linear, time-varying, discrete-time systems. The systems under consideration have time-varying norm-bounded parameter uncertainties in both state and input matrices. Robust controllers are assumed to be available by using guaranteed cost control approach. The main contribution is in the derivation of explicit block structured conditions on complementary matrices of systems and controllers within the expansion-contraction scheme. A particular selection procedure for complementary matrices is included.
