During the operating of tunnel boring machine, the
unbalanced force of each motor in cutterhead drive system would cause component
damage or even system malfunction. Hence, the structure and control mode of the
cutterhead drive system are analyzed, the motor vector control model is
established, and an improved coupling control structure is proposed for
cutterhead drive system. The motorgiven speed selection function
is equipped on the structure to eliminate the synchronous error caused by the
delay in the starting stage, and the speed compensation coupling strategy is
adopted to reduce the speed difference between motors. Furthermore, the neural
network PI controller is designed to control the running speed of each motor,
which helps the control system to adjust the control parameters adaptively
according to the load variation and improve the control accuracy. Finally, the
synchronization effect of the proposed adaptive coupling control is compared
with that of masterslave control and parallel control
by establishing a Simulink simulation model, and the comparison results show
that the proposed adaptive coupling control method can make each link in the
control cooperate with each other and can achieve better control performance
and response speed．
