设计1套自主控制能力较强的舰船直流电机转速自稳定控制系统。采用PID控制量增量缩小化处理、引入电流截止负反馈、优化硬件电路设计等方法提高控制系统对电机转速控制的自稳定性和保证系统工作的安全性。该系统能够实现硬件软启动控制、电枢过流保护、抗电网电压波动等功能，试验证明该系统能够控制电机在既定的转速下平稳运行。
A speed self-stabilization control system with strong self-control ability is proposed.A series of methods like reducing the control quantity of PID,introducing current cutoff negative feedback and optimizing the circuit are taking to improve the stability of the speed and to ensure the safety of the system during operation. The system can realize DC motor soft-start through soft control,over-current protection,anti-supply voltage fluctuation and other functions.The test proves that the system can make the motor run smoothly at a given speed.
