Motion scaling on one- and two-axis compensatory control tasks

Abstract: One-and two-axis compensatory control tasks were performed both with and without motion inputs. Additional tests were made in which the motion input, compared with the visual input, was reduced in scale. L i t t l e o r no difference in error measurements was observed in the single-axis-motion/no-motion tests. However, a decrease in normalized tracking error and an increase in the closed-loop system frequency were observed when motion was added to the two-axis tests. In the tests with reduced motion scale, the… Show more

“…Performance degradation is also reflected in the decreased crossover frequency. Whereas some studies suggest a degradation ratio in relation to the corresponding single axis ω c such as 1/ √ 2 [10], such a consistent ratio has not been found here.…”

“…1) Performance degrades in dual-axis tasks compared to the independent single axis tasks, indicated through an increase in error variance, a smaller crossover frequency, and a smaller phase margin [1], [7], [17]. 2) Performance degradation in dual axis is smaller with physical motion [10], which can be indicated by a decrease in error variance, an increase in crossover frequency and an increase in phase margin. 3) Asymmetrical human control behavior in each axis can be seen from unequal HC parameters in each axis, as well as from differences in error variance, control variance, crossover frequency, and phase margin between the roll and pitch axis [9], [1].…”
