摘要： An engine testing system has a torque control system which controls at least one of an axial torque and an engine load torque. The torque control system comprises a mechanical transfer function which receives an engine torque and a current and outputs an engine speed, the axial torque and a dynamo speed, an electric transfer function which receives a command current and outputs the current, and a torque controller which receives one of a command axial torque and a command engine load torque, and at least one of the engine speed, the dynamo speed, and the axial torque and outputs the command current. A transfer function representative of the torque controller is designed using the structured singular value synthesis method so as to be adapted to the mechanical transfer function and the electric transfer function.
