Abstract:

The modeling, analysis and digital simulation of an analog servo controller and its successful application to a full-scale airframe fatigue tests is described. Primary emphasis is on the use of minicomputers for dynamic load control of multiple channels. Hardware and software used to generate functions and control load is described. A brief comparison of digital system performance versus conventional analog controllers is included.
