The human performance in a man-machine system, has been investigated for a given condition in a given system. Therefore, the forms and the constants of the transfer function representing the performance are different as reported in the publication of many researchers who have worked with various conditions or systems. The human performance will not be the same always, but will be much variable.
In this paper, human tracing performances for 4 operators are measured for simple servomechanisms in which the frequency of a harmonic input is changeable. As a result, it is found that the measured transfer functions are different from the previous transfer functions, so long as a dead time of 0.2sec is included in the function. The proportional constant of the present transfer function is found to be a function of the frequency, and the function is also found to include such prediction as derivative performance. The transfer function is theoretically derivative here. As the frequency increases, the lower order derivative performance may change to one having an element of higher order derivative performance. moreover to one having a negative dead time in order to be consistent with some measurements, although personal differences appear in the higher frequencies.
