ABSTRACT:
Methods for analyzing system operator coupling susceptibility are described herein. In one embodiment, an open loop frequency response can be compared to a related over-steer point. An over-steer point can be the condition where, as operator gain is increased for an open loop system, the corresponding closed loop gain at a corresponding resonance peak increases by at least approximately the same amount as the increase in operator gain or at least approximately a selected larger amount than the increase in operator gain. In other embodiments, an open loop frequency response can be compared to a critical gain rate. The critical gain rate can be the rate of change of open loop gain per open loop phase angle of the corresponding open loop system response at an over-steer point that is associated with a zero decibel closed loop gain.
