The invention discloses an elevator driving control system which comprises a dynamic torque controller, a static torque controller, a current instruction generator and a current controller. The dynamic torque controller generates a dynamic torque instruction according to the change of the speed instruction; the static moment controller generates a static moment instruction according to the tracking error of the actual speed of the lift car to the speed instruction, and the static moment instruction is used for eliminating the tracking error of the actual speed of the lift car to the speed instruction on the basis of the dynamic moment instruction; the current instruction generator is used for generating and outputting a current instruction for driving the motor according to the dynamic torque instruction and the static torque instruction; and the current controller is used for controlling the driving elevator according to the current instruction and the actual current of the driving motor, so that the actual current of the driving motor tracks the current instruction. High-performance control over the elevator driving motor can be achieved under the condition that transmission delay exists in transmission of elevator car detection information from a car to a control cabinet.
