The invention relates to the technical field of hydraulic pressure, and provides a boom angular velocity determination method and device, electronic equipment and a storage medium. The method for determining the angular velocity of the cantilever crane comprises the following steps: acquiring the angular velocity omega of the cantilever crane during rotation and the current angle parameter theta of the cantilever crane; the flow Q cylinder flowing out of the rodless cavity theoretically, namely the flow Q cylinder flowing through the balance valve, of the oil cylinder is calculated based on the angular velocity omega and the angle parameter theta; the pressure difference P of the two sides of the balance valve is obtained; and based on the flow Q cylinder flowing through the balance valve, the pressure difference P and the characteristics of the electromagnetic valve, control current needing to be input into the electromagnetic valve is determined, and the control current is input into the electromagnetic valve to control the arm support to rotate at the angular velocity omega. According to the technical scheme, the problem that the longer the boom is, the faster the angular speed is is solved. According to the method for determining the angular velocity of the boom, under the condition that the opening degrees of the operating handles are the same, the longer the boom is, the smaller the angular velocity is, and the safety of working machinery is improved.
