Embodiment Construction
[0098] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0099] Establish a two-layer structure of the cutter head speed control layer and the drive shaft torque coordination layer, such as figure 2 As shown, the cutter head speed control layer solves the problem of cutter head speed stability in the case of cutter head load interference, and obtains the base torque of the drive motor. The problem of unbalanced distribution of drive shaft torque under the condition of backlash interference when the ring gear is meshing is to find the torque coordination amount of each drive motor. The sum of the base torque and the torque coordination amount is the actual input torque of each drive motor.
[0100] The control algorithm of the cutter head speed cont...
