Abstract
The dynamic behaviour of a harmonic drive, in particular the non-backdrivability, is developed in terms of a sensitivity transfer function (or 1/impedance). The instrumentation of the harmonic drive with torque sensor is described. This leads to a description of the control algorithm which allows modulation of the sensitivity transfer function within the limits established by the closed-loop stability criteria. A set of experiments on an active hand controller, powered by a DC motor coupled to an instrumented harmonic drive, is given to verify the theoretical predictions
