actuator cannot be controlled. At the beginning of the slew, the resulting command-position delta is high enough to<br />
cause equalization to be entered and thus shows the same observations as the United <strong>Space</strong> Alliance test.<br />
Equalization is not modeled in the SIMULINK model and the presence of equalization would have helped control<br />
the actuator during the slew.<br />
