FIELD: construction equipment.
SUBSTANCE: invention relates to construction equipment. In the boom oscillation control method, the first input signal is received from the handle and the first input signal is generated to obtain the second input signal for limiting the amplitude coefficient of the residual oscillations of the boom so that it does not exceed the threshold amplitude coefficient of the residual oscillations. A hydraulic drive flow rate request signal is determined to actuate the boom in accordance with the second input signal and the maximum flow rate of the hydraulic drive. The voltage input signal of the flow control valve connected to the hydraulic actuator is determined in accordance with the flow request signal and the flow compensation function. The flow compensation function is an inverse function of the flow characteristic curve function of the flow control valve. Control the flow control valve so that it operates in accordance with the input voltage signal.
EFFECT: possibility of controlling the swing of the boom is realized.
