Multi-loop Pilot Behavior Identification in Response to Simultaneous Visual and Haptic Stimuli

Abstract: The goal of this paper is to better understand how the neuromuscular system of a pilot, or more generally an operator, adapts itself to different types of haptic aids during a pitch control task. A multi-loop pilot model, capable of describing the human behaviour during a tracking task, is presented. Three different identification techniques were investigated in order to simultaneously identify neuromuscular admittance and the visual response of a human pilot. In one of them, the various frequency response fun… Show more

“…It should be noticed that a driver with stiffness close to infinity, that is keeping the steering wheel exactly in the center, would produce the same vehicle trajectory that the DHA system produces when the pilot is not holding the steering wheel (i.e. when he has zero stiffness) [13]. The IHA controller, in its internal structure, was designed in the same way as the DHA, except for the force gain of the haptic subsystem which must have the opposite sign; this way, the force feedback commanding the steering wheel is perceived as a disturbance by the operator.…”

“…The dynamics of the whole neuromuscular system are determined by the settings of these components. Humans are able to adapt the neuromuscular dynamics to the task they perform [2]- [4]. In realistic control situations, e.g., during postural control or driving tasks, humans vary their admittance continuously depending on the external environment [6].…”

“…The dynamics of the neuromuscular system play an important role when trying to investigate the effect of haptic aids on pilot behavior [2]. Previous works have investigated methods to estimate the neuromuscular system during force-related tasks [3] or more complex control tasks [2], [4], [5]. However, a key limitation with much of the literature is that the estimation methods assume a time-invariant neuromuscular response.…”

“…In a control task with haptic and visual cues, two different dynamic responses need to be investigated: the visual response and the neuromuscular response [20,21]. The visual response describes the pilot response to the visual cue, whereas the neuromuscular response represents the dynamic settings of the pilot's arm and determines how the pilot interacts with forces (from disturbances or from haptic aids).…”
