HUMAN PILOT DYNAMICS WITH VARIOUS MANIPULATORS.
Abstract
The purpose of the experimental efforts is to explore on a preliminary basis the limiting characteristics of the human operator's 'actuator' or neuromuscular system dynamics as affected by the manipulator. The effects of three manipulators (pressure, free-moving, and spring-restrained) on system performance and the human operator's describing function are presented for three controlled elements and two high bandwidth forcing functions. Describing function differences are primarily in the phase, i.e., the effective time delay at high-frequency and an effective phase lag at very low frequencies. Generally the mean square error and describing function results for the spring-restrained manipulator were intermediate to those for the free-moving (no spring) and the pressure (infinite spring) manipulators. The pressure controller gave lower mean square error and less effective time delay than the free-moving controller. In addition, the effective phase lag at very low frequencies was either the same as or larger than that for the free-moving control. (Author)
