Experimental results of the PMSM driven V-belt CVT system using the well-known PI controller at 376.8 rad/s (3600 rpm) case under the lumped nonlinear external disturbances with twice parameter variations : (a) tracking response of command rotor speed , desired command rotor speed , and measured rotor speed ; (b) response of tracking error ; (c) response of tracking error amplification.
