Flight-Test Evaluation of ACM Controller at 75RPM, on Spacecraft 9433, April 13-16, 1976.

Abstract

This report presents an analysis, recommendations, and conclusions of flight data from Spacecraft no. 9433 taken during tests conducted following the implementation of the Automatic Control Mode (ACM) on April 13, 1976. The analysis had predicted that the tightest error control that could be hoped for at 75 RPM was approximately plus or minus 2.5 degrees, and this was confirmed by the flight data. The final recommended gains at 75 RPM are a position gain 'A' of 6 or 7, and a rate gain C of 0 to 8. General conclusion on the overall performance of ACM was that it can indeed maintain continuous control for longer periods of time than the normal mode. (Author)
