<p>Provided is a dynamometer system provided with a shaft-torque meter, and capable of an equivalent evaluation to that of a system provided with a load cell. A dynamometer system is provided with an encoder for detecting the angular velocity, a shaft-torque meter for detecting the shaft torque, and a control device (6A) for controlling the dynamometer on the basis of the angular velocity (omegaM) of the dynamometer and the detection value (Tsh) of the shaft-torque meter. The torque-control device (6A) is provided with: a computed-torque calculation unit (61A) for calculating a computed-torque value (Tcal) by adding the detection value (Tsh) to a value obtained by multiplying the angular acceleration (omegaMss) by the moment of inertia (JM); and a computed-torque controller (62A) for calculating a torque-current-command value (Tdyref), on the basis of an externally inputted command value (Tref) and a computed-torque value (Tcal).</p> |
