Abstract
A simple approach for disturbance attenuation in multivariable linear systems via dynamical output compensators is proposed based on complete parametric eigenstructure assignment. The basic idea is to minimise the H/sub 2/ norm of the disturbance-output transfer function using the design freedom provided by eigenstructure assignment. The closed-loop eigenvalues are also optimised within desired regions on the left-half complex plane. Application of the proposed approach to robust control of a magnetic bearing is considered.
