Abstract: Hysteretic equalization means are disclosed for equalizing or matching the outputs of two or more servovalves operating simultaneously in a multi-channel or redundant servopositioning apparatus. Such equalization avoids system deadzone and reduces the transient that may occur upon shut-off of one servovalve. The equalization is accomplished by feeding back the interchannel mismatch through means having a hysteresis characteristic.
