发明名称 ANTI-REBOUNDING CONTROL APPARATUS AND METHOD IN AN ELECTRICAL SWING SYSTEM OF A HYBRID EXCAVATOR
摘要 An anti-rebounding control apparatus is provided, which includes an anti-rebounding controller outputting a first command for setting a torque limit value to "0" if an electric motor speed value is equal to or smaller than an upper threshold value and equal to or larger than a lower threshold value in the case where a speed command value of "0" is input and outputting a second command for setting the torque limit value to a maximum value if the electric motor speed value is smaller than the lower threshold value, a torque regulator setting the torque limit value to "0" when the first command is input and setting the torque limit value to the maximum value when the second command is input, and an electric motor inverter intercepting a power that is supplied to an electric motor if the torque limit value is set to "0" and re-supplying the power to the electric motor if the torque limit value is set to the maximum value. Accordingly, the same performance as an anti-rebounding system that is used in a swing system of an existing hydraulic excavator can be implemented even in a system that performs a swing operation using an electric motor such as a hybrid (or electric) excavator.
