PROBLEM TO BE SOLVED: To provide the dynamo controller of a dynamometer system which can reproduce an unloaded state with high accuracy when an engine is started.SOLUTION: The dynamo controller of a dynamometer system includes controllers Gc1, Gc2 designed by a control system design method called as a H ∞ control or μ design system in such a manner that a response from an external input w to a control amount z is made small for a generalized plant Pa which outputs observation outputs y1, y2 and a control amount z from the external input w and a control input u equivalent to a torque current command to an inverter. The generalized plant Pa includes a dynamic characteristic model 7 which identifies characteristics of the dynamometer system in such a manner that an angular acceleration of an engine is outputted from the external input w and the control input u. A control amount z is a differential between an angular speed of an engine as a single body calculated based on the external input w and the angular speed of the engine calculated by a dynamic characteristic model 7. |
