Abstract

Of the methods on power-matching control of hydraulic excavator now, the rotary inducing control is commonly used but has shortcoming of response lag. According to the dynamic characteristics of diesel engine and hydraulic pump in power system of hydraulic excavator, method of constant torque control combined with rotation speed feedback control is proposed, the system simulation model is established in Simulink, with the load signal in actual condition imported to the model, the two control methods are analyzed. The result indicate that the method of constant torque control combined with rotation speed feedback can stabilize the engine's speed and reduce the maximum lose of engine speed, make the hydraulic pump can make full use of the engine, so that elevate the excavator's effect.
