| Abstract: | Necessary and sufficient conditions of robust stability are derived for multivariate perfect model matching systems under external disturbances and plant perturbations (non-linear, linear feedback perturbations and fractional perturbations). The derived results also provide an intuitive insight into controller effects on robustness. A general parametrized 2-D controller is introduced to stabilize the nominal plant. |
