This paper examines the control strategies that humans use to interact with an unknown nonminimum-phase system. We present results from an experiment in which 3 human subjects interact with an unknown nonminimum-phase system 40 times over a 1-week period. We use subsystem identification to model the control strategies that each subject uses during each trial. In particular, we identify feedback and feedforward controllers that model the subjects' control strategies. The identified controllers suggest that the subjects learn to approximate and use the inverse plant dynamics (over a finite frequency range) in feedforward even though the plant is nonminimum phase.
