The invention discloses a swinging optimal control system for a bridge-type container crane. The swinging optimal control system is composed of a traction motor, a container position sensor, an analog-digital converter, a digital-analog converter, a field bus network, a distributed control system (DCS), a control room display and a traction motor controller. A control room engineer designates theposition needing to be reached and loading and unloading time of a container. The DCS outputs a control strategy capable of making the container loading and unloading swinging energy be minimal at this time by executing an inner optimum control algorithm and further converts the control strategy into a control instruction of the traction motor, and the control instruction is sent to the traction motor controller through a field bus network. The motor controller outputs the controlled quantity through the analog-digital converter so that the traction motor can execute corresponding movements. Meanwhile, the position se
