针对船舶动力推进系统加速性能控制方法实施改进优化。首先，设计船舶动力推进系统加速性能控制模型，通过推进电机推力控制与桨距的调节共同实现推进系统的加速性能控制。船舶集控室将加速命令传输至VDF中央处理单元后，推进变频器内的PLC软件获取获取控制命令，利用模糊控制器控制加速电机转速。针对控制偏差问题，采用遗传算法改进模糊控制器，通过准确控制电机产生的推力实现加速性能控制；VDF中央处理单元获取控制信息后，将螺距控制信息传输至CPP处理单元，由此实现对螺距的控制。实验结果显示，该方法能够有效实现研究对象的加速性能控制，控制响应时间在1 s内，且在联控模式控制过程具有较强的抗干扰性。
Improvements and optimizations are implemented for the acceleration performance control method of ship propulsion systems. Firstly, design an acceleration performance control model for the ship's propulsion system, which achieves acceleration performance control of the propulsion system through the combination of propulsion motor thrust control and blade pitch adjustment. After the ship control room transmits the acceleration command to the VDF central processing unit, the PLC software inside the frequency converter is pushed to obtain the control command, and the fuzzy controller is used to control the speed of the acceleration motor. To address the issue of control deviation, a genetic algorithm is used to improve the fuzzy controller, which achieves acceleration performance control by accurately controlling the thrust generated by the motor; After obtaining control information, the VDF central processing unit transmits the pitch control information to the CPP processing unit, thereby achieving control of the pitch. The experimental results show that this method can effectively control the acceleration performance of the research object, with a control response time of less than 1 second, and has strong anti–interference ability during the joint control mode control process
