为了保障盾构刀盘驱动系统能够稳定运行，刀盘驱动电机之间的同步性能是一个关键因素。针对盾构电机数量多、结构复杂的特点，分析主从控制、并行同步控制和几种耦合控制在盾构驱动电机控制应用中的优缺点，说明并行同步在应用中的合理性；设计一种模糊PID智能控制算法，提出模糊PID控制器与并行同步控制结构相结合的盾构刀盘驱动多电机同步控制策略，应用Matlab／simulink进行建模仿真，对该控制策略和常规的PI控制进行仿真对比。结果证明：所提出的控制策略的动态响应快、实时性能好，在相同的负载突变状况下，该方法具有更强的鲁棒性，能更好地使多电机以设定速度同步运行。

The synchronous performance of the cutter head driving motors of shield is the key to the normal operation of the cutter head drive system of shield.In this paper,the advantages and disadvantages of master-slave control,parallel synchronous control and coupling control of driving motors of shield are analyzed,and the rationality of parallel synchronous control is demonstrated.A multi-motor synchronous control method based on fuzzy PID controller and parallel synchronous control structure is proposed and simulated by means of Matlab/simulink module,and comparison and contrast is made between the mentioned control method and PI control.The study shows that the mentioned control method is superior to PI control in terms of dynamic response,real-time performance and robustness,and it can achieve better synchronous working of the motors at the set speed.
