摘要： Provided is a dynamometer system dynamo control device that can accurately reproduce a no-load state. The dynamo control device includes controllers that are designed, using a H-infinity control or a μ-design method, such that, for a generalized plant that outputs observation output and a controlled variable from external input and from control input, the response from the input until the variable is shortened. The generalized plant includes a dynamic characteristics model wherein the characteristics of a dynamometer system are identified such that the angular acceleration is output from the external input and the control input. The controlled variable is the difference between the angular acceleration calculated for an engine alone on the basis of the external input and the angular acceleration calculated by the dynamic characteristics model.
