Description

technical field [0001] The present invention relates to the technical field of engines, in particular to a method and device for predicting a rotational speed based on dynamic characteristics of an engine. Background technique [0002] During the working process of cranes and excavators, the engine may have a large difference between the actual working speed and the target speed, which may cause vibration, speed drop, or even flameout during the working process of cranes and excavators, causing safety accidents. [0003] Therefore, at present, most companies or scientific research institutions have conducted a lot of research on the characteristics of the engine. However, on the one hand, the current research on engine characteristics generally adopts the static research method. Since the engine is in dynamic changes in the actual application of the engine, the static research on the engine is not suitable for the actual application of the engine. At the same time, it is ge...
