<p>Provided is a test system capable of stable torque control even at a higher frequency than the control band of a torque controller. A test system is provided with: an excitation torque command calculation unit (61) which calculates an excitation torque command value on the basis of the command values of excitation frequency and excitation amplitude that are inputted from the outside; a shaft torque command calculation unit (62) which defines a value obtained by adding up a base torque command value inputted from the outside and the excitation torque command value as a torque command value; a shaft torque controller (63) which determines a first control input value such that a shaft torque detection value becomes the shaft torque command value; a feedforward input calculation unit (64) which defines a value obtained by removing components equal to or less than a predetermined frequency from the shaft torque command value as a second control input value; and an addition unit (65) which defines a value obtained by adding up the first and second control input values as a torque current command value. The excitation torque command calculation unit (61) calculates the excitation torque command value such that the deviation between an amplitude value calculated on the basis of the torque detection value and the excitation amplitude command value is eliminated.</p> |
