Title:
METHOD FOR CONTROLLING ENGINE BENCH SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/146234
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a method for controlling an engine bench system, with which it is possible to suppress resonance using a simple preliminarily experiment and a small computational load. This method for controlling an engine bench system is provided with: a speed control step in which speed control of a dynamometer is executed while an engine is maintained in a non-ignition state, and in which the speed control is ended when the rotational speed of the dynamometer has increased to a prescribed speed; a measuring step in which a shaft torque detection signal is acquired during a period from when, as a result of inertia, the rotational speed of the dynamometer is a prescribed measuring start speed until said rotational speed reaches a prescribed measuring end speed; a frequency analyzing step in which the frequency of the signal having the strongest intensity, from among the shaft torque detection signals acquired in the measuring step, is acquired as a resonant frequency; a design step in which a control gain of a dynamometer control device is determined using the acquired resonant frequency; and a dynamometer control step in which the dynamometer is controlled using the dynamometer control device of which the control gain has been determined.
