“…Multiple investigations have clearly found a degradation in performance with dual axis in comparison to single axis tasks [1], [7], [17]. In fact, the relation between crossover frequency (the frequency up to which the HC is able to track) and the number of axis was postulated to be proportional to the reciprocal of the square root of the number of axis [18]. That is, with dual axes, the crossover frequency is 1/ √ 2 of that of the single axes case.…”

“…In Ref. 6 it is shown that in the multiloop control task of lunar module hover, where the outer-loop variable is horizontal translation and the inner-loop variable is pitch angle, that the series arrangement of the pilot model does give a true representation of human pilot response. In this task the outer-loop dynamics were where a small time delay is used instead of a lag function.…”

“…If the control task is a multiloop problem, where there is a second variable (such as altitude or horizontal displacement) which is controlled by the manipulation of an innerloop variable (such as pitch angle), it is necessary to specify an outer-loop pilot model in It was also shown in reference 6 that the lag function included in the outer-loop pilot model is not really required to properly represent the pilot. The outer-loop variable (horizontal translation) is controlled at such a low frequency that a lag of the magnitude of 0.1 second does not influence the closed-loop response.…”
