Modulator needed by the servo valve
Information
The Modulator block is needed by the servo valve. Each of the four valve flows, q1, q2, q3, and q4, is characterized by an underlap, x0. Each of the four flows is proportional to either x0 + x or x0 - x, depending on the topology. These two proportionality factors are computed by the Modulator block. They are used as modulation signals in the four hydraulic conductor models representing the turbulent valve flows.
