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 H2 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
