Dynamic modeling of a 6-degree-of-freedom Stewart platform driven by a permanent magnet synchronous motor
For an electrical six-degree-of-freedom Stewart platform, it is difficult to compute the equivalent inertia of each motor in real time, as the inertia is time-varying. In this study, an analysis using Kane’s e...
