ENGINE SPEED CONTROL METHOD, CONTROL SYSTEM AND JIB-TYPE ENGINEERING MACHINE |
摘要 |
<p>In one aspect of the invention, an engine speed control method used to control an output speed of an engine of a boom-type engineering machine during a boom action includes: detecting a load pressure of a hydraulic system and a moving speed of a boom; determining a target speed of the engine according to the load pressure and the moving speed of the boom, by a central control unit; and sending, by the central control unit, the target speed of the engine to an engine control unit, and performing, by the engine control unit, a speed closed-loop adjustment according to a current speed value fed back by the engine, so that a current speed of the engine is consistent with the target speed of the engine. Further aspects are an engine speed control system and a boom-type engineering machine having the engine speed control system.</p> |
