Title:
DYNAMOMETER SYSTEM CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/207832
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a dynamometer system control device that can perform control with high responsiveness and stability and can perform highly accurate measurements even when the configuration of a load connected to a dynamometer body is changed. Provided is a dynamometer system control device that comprises: a mechanical loss arithmetic unit 48 that generates a loss compensation signal corresponding to loss torque generated in a dynamometer body in a state where a load is connected, on the basis of an angular velocity detection signal; a characteristic vibration suppression control circuit 43 that generates a compensation signal in order to suppress a characteristic vibration of a swinging element; and a torque current command signal generating unit 49 that generates a torque current command signal by subtracting the compensation signal from an upper level torque command signal. The characteristic vibration suppression control circuit 43 is provided with a normative model arithmetic unit 432, a deviation compensator 433, a model input generating unit 434, and a differential compensator 437 that generates a correction signal by subjecting a torque signal obtained by the normative model arithmetic unit 432 to a differential operation.
