The interaction of control gain and vibration with continuous manual control performance
The interaction of control gain and vibration with continuous manual control performance
The interaction of the effects of control gain and 4 Hz vertical (z-axis), whole-body vibration at 0·75 m/s2 rms on human operator performance in a simple manual tracking system was investigated with four different controls. The controls were isotonic (displacement) and isometric (force) joysticks and knobs. Performance analysis includes calculation of closed-loop human operator transfer functions, components of error correlated with the tracking input and vibration and operator generated noise. The optimum control gains for minimizing tracking error under vibration were found to be lower than in static conditions due to increases in vibration-correlated error and operator-generated noise, which both tend to be proportional to control gain.

Abstract
The interaction of the effects of control gain and 4 Hz vertical (z-axis), whole-body vibration at 0·75 m/s2 rms on human operator performance in a simple manual tracking system was investigated with four different controls. The controls were isotonic (displacement) and isometric (force) joysticks and knobs. Performance analysis includes calculation of closed-loop human operator transfer functions, components of error correlated with the tracking input and vibration and operator generated noise. The optimum control gains for minimizing tracking error under vibration were found to be lower than in static conditions due to increases in vibration-correlated error and operator-generated noise, which both tend to be proportional to control gain.
