Abstract
This paper considers an internal model control scheme for multi-input multi-output systems which contain unknown parameters in the coefficient matrices of the state equations. The internal model is adaptively constructed from input and output signals of the plant. We first propose a linear parametric representation for the unknown multi-input multi-output systems. Then, we present an adaptation method such that the output of the internal model is asymptotically identical to that of the plant, guaranteeing stability of the closed-loop system.
