The invention provides an elevator driving control system based on multi-objective optimization. The elevator driving control system comprises an AC power supply, a rectifying circuit module, a current sensor, a voltage sensor, a position sensor, an upper computer, a DSP control system, a driving module and a traction machine, wherein the DSP control system comprises a DSP control module, a CAN bus module, a signal acquiring and conditioning module and a signal isolation output module. The DSP control module further comprises a velocity curve module, a current control module, a cage position control module, a torque control module and a low-power-consumption module. The upper computer transmits position information to the DSP control module through a CAN bus. The DSP control module performs decision according to the position information and transmits a corresponding control signal to the driving module. The driving module drives the traction machine to operate according to the received control signal, thereby realizing motor speed adjustment and achieving a purpose of operating the elevator. According to the elevator driving control system, multiple aspects such as dynamic characteristic, restraining condition and steady-state accuracy of the elevator system are comprehensively considered, and elevator driving control technology based on multi-objective optimization is supplied.
