Optimal two-degree of freedom controllers
L. Keviczky, Csilla Bányász · 1998
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 /spl Hscr//sub 2/- and /spl Hscr//sub /spl infin//-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.
