This paper presents a servo strategy of Generalized Minimum Variance Control (GMVC) with a two degree of freedom. If GMVC fasts the transient response by tuning the control signal weight of the cost function, an overshoot remains. This paper introduces the two degree of freedom GMVC. The two degree of freedom function curbs the overshoot, while the satisfactory transient characteristic holds. This paper presents two type methods for two degree of freedom: One is setting a reference signal filter in the feedforward part of the closed loop systems, the other is setting a rational function into the cost function. This paper recommends two degree of freedom method with the rational function for the simplification.
