摘　　要：传统舰船主机供油单元控制方法,存在供油缸体油量控制精度误差过大的问题。导致供油链路控制数据无法准确识别输出的实际油量,造成舰船动力控制异常。为了解决油量控制问题,提出嵌入式技术下舰船主机供油单元控制分析。根据供油单元中油腔阀体工作状态,对其建立伸缩模型;根据模型数据,对控制器控制逻辑变量进行定义;最后,根据新定义参量,完成对供油控制单元控制参量的更新,从而实现高精度油量控制的效果。通过与传统控制方法的多油量测试表明:提出的控制方法就能够满足不同油量,多次连续性的高精度供给控制,油量控制精度达到97.8%以上。Traditional control method is the accuracy of oil unit control.Therefore,the oil supply link control data can not accurately identify the actual oil volume output,resulting in abnormal ship power control.In order to solve the oil control problem,the analysis of embedded technology.Set up the expansion model of the working state in the oil supply unit,define the controller control logic variables according to the model data;finally,update the control parameter of the oil supply control unit to realize the effect of high-precision oil quantity control.The multi-oil volume test with traditional control method shows that the proposed control method can meet different oil quantity,high precision supply control,and oil quantity control accuracy above 97.8%.
