The aerial work platform includes a chassis, a basket, a hydraulic lifting structure and a hydraulic system. A control unit includes a circulation circuit, an electric motor pump and a flow regulator. To simultaneous displace two different parts of the lifting structure, the actuators are divided between first and second groups and the control unit determines first and second target flow rates, while controlling the motor pump with a delivery flow rate greater than or equal to the sum of the target flow rates. The control unit controls the flow rate controller to send toward the groups a regulated proportion of the fluid from the motor pump, presenting a flow rate equal to the sum of the target flow rates, and then to divide this regulated proportion into two adjusted parts, respectively presenting the first and second target flow rates and respectively sent to the first and second groups.
