Abstract :
This paper presents the optimality of a generic form for two-degree of freedom controllers. The optimality is expressed by two simple serial compensators and can be performed in ℋ2- and ℋ∞-norm space. It is shown how these filters (depending on the reference signal), the output disturbance and the invariant process factors should be selected by the solutions of Diophantine equations
