摘　　要：为适应现代火炮结构紧凑型设计,满足现代火炮随动驱动系统大功率和大惯量的需求,提出了三电机交流驱动控制。针对三电机火炮驱动系统同步性能因受力不平衡及扰动因素的影响,建立了三电机交流驱动系统控制模型,采用主从电机控制模式,使得三电机的控制主令相同,为三电机的同步控制提供了基础。在此基础上提出了三电机差速反馈控制,解决了因各个电机受力不平衡及扰动因素使得驱动无法同步的问题。仿真结果表明,该方法能够实现三电机同步驱动,克服电机受力不均引起的转速不同步。The three motors AC drive system synchronous technology was studied. The three-motor control system model was established. By use of the master-slave motor control mode, make the three-motor to receive the same control master order so as to ensure synchronous control of the three-motor. On basis of this, a kind of three-motor differential speed feedback control was proposed. This method can solve the problem that speed of the motor can not be synchronized because of the uneven force of the motor, and the method has the value of engineering application.
