DYNAMOMETER SYSTEM

WIPO Patent Application WO/2015/053220

A1

Provided is a dynamometer system dynamo control device that can accurately reproduce a no-load state when an engine is started. The dynamometer system dynamo control device includes controllers (Gc1, Gc2) that are designed, using a control system design method designated as H-infinity control or a μ-design method, such that, for a generalized plant (Pa) that outputs prescribed observation output (y1, y2) and a controlled variable (z) from external input (w) that corresponds to the engine torque generated by an engine and from control input (u) that corresponds to a torque current command given to an inverter, the response from the external input (w) until the controlled variable (z) is shortened. The generalized plant (Pa) includes a dynamic characteristics model (7) wherein the characteristics of a dynamometer system are identified such that the angular acceleration of the engine is output from the external input (w) and the control input (u). The controlled variable (z) is the difference between the angular acceleration calculated for an engine alone on the basis of the external input (w) and the angular acceleration calculated for the engine by the dynamic characteristics model (7).
