Title:
DYNAMOMETER CONTROL DEVICE AND METHOD FOR ESTIMATING MOMENT OF INERTIA USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/114233
Kind Code:
A1
Abstract:
To provide a dynamometer control device whereby excitation control can be performed so that a resonance phenomenon does not occur even when the moment of inertia of an engine is unknown. A dynamometer control device 6 is provided with an excitation signal generating unit 61 for generating a randomly or periodically fluctuating excitation signal, a speed controller 62 for generating an input signal to a dynamometer whereby a dynamo rotation speed matches a predetermined dynamo command rotation speed, a shaft torque compensator 64 for generating an input signal to the dynamometer whereby vibration of a shaft for connecting an engine and the dynamometer is suppressed using the detection value of a shaft torque sensor, and an adder 65 for generating a torque electric current command signal by adding the input signals generated by the speed controller 62 and the shaft torque compensator 64 to the excitation signal.
