Abstract
Method and system that produce requisite drive signals to fully exercise and test electromechanical elements of a liquid rocket stage including solenoid valve drives, DC motor drives and actuator drive signals. The electrical driver tester includes a signal processor, power driver circuits, and A/D and D/A circuits to monitor and control the drive circuitry. Drive current is monitored and a signal proportional to the current is produced for the purpose of analyzing current profiles as part of the test regimen for the device under test. Actuator speed and positioning are controlled in real time with a tailored lead lag control algorithm implemented with digital signal processor hardware.
