摘　　要：通过构建真实反映船舶螺旋桨负荷特性的船舶电力推进动态负荷半实物在环仿真系统,研究船舶电力推进相关技术是一种可行和高效的研究手段。所构建的半实物在环仿真系统核心是一台运行螺旋桨动态负荷数学模型并输出控制量和仿真结果的数字仿真机。根据系统对实时性的要求,提出了以DSP+MCU嵌入式系统作为该数字仿真机,并描述了DSP+MCU嵌入式系统硬件、软件的具体结构和设计要点。最后通过仿真系统实验,证明了DSP+MCU嵌入式系统完全满足此处的应用要求。Research on marine electric propulsion techniques by means of developing a marine electric propulsion dynamic load Hardware-In-the-Loop emulation system, which can really act as marine propeller characteristics, is a feasible and efficient way. The core of the founded Hardware-In-the-Loop emulation system is a digital simulation computer running propeller dynamic toad mathematical model, outputting control signals and simulation results. According to real-time requirement, DSP＋MCU embedded system is put forward as the digital simulation computer. The hardware structure, software architecture and design main points of DSP＋MCU embedded system are described. Finally, the result of the emulation system experiment proves DSP＋MCU embedded system entirely meets the requirements of this application.
