Abstract :
Two reference-input tracking problems that involve arbitrarily-small tracking error for time-varying inputs, and asymptotically-zero tracking error for constant inputs, are formulated for square, invertible linear plants. Conditions for solvability (via high-gain feedback) are given in terms of plant transmission zeros. Simplifications in the geometry of almost invariant subspaces for plants that satisfy the conditions are exploited to obtain explicit control law constructions.
