Abstract:

SIX SUBECTS PERFORMED A SIMULATED AIRCRAFT TRACKING TASK USING EACH OF TWELVE CONTROL CONDITIONS RESULTING FROM COMBINING FOUR LEVELS OF CONTROL BACKLASH AND THREE LEVELS OF GAIN. THE EXPERIMENTAL FINDINGS DEMONSTRATED A SIGNIFICANT INTERACTION BETWEEN THE EFFECTS OF BACKLASH AND GAIN ON SYSTEM PERFORMANCE. THAT IS, THERE WAS A MONOTONIC INCREASE IN SYSTEM ERROR WITH INCREASING BACKLASH AT ALL LEVELS OF GAIN. HOWEVER, THE HIGHER THE GAIN THE GREATER THE RATE OF INCREASE. THE IMPLICATIONS OF THESE RESULTS FOR THE DESIGN OF MANUAL CONTROL SYSTEMS WEREDISCUSSED BRIEFLY.
