| 摘 要： | 为了提高船舶电站柴油机调速系统的动态精确度，抑制负荷的扰动，通过建立柴油机及其调速系统的数学模型，并对其加以分析，设计了船舶电站柴油机调速系统的�H�∞�控制器。通过对实际的船舶电站柴油机调速系统进行Matlab仿真计算分析发现：当外界环境条件改变，即当系统参数发生摄动时，相比于其他的状态反馈控制系统，所设计的�H�∞�控制器能够有效地提高柴油机调速系统的动态精确度和抑制扰动的能力，从而改善船舶电力系统频率的稳定性，提高船舶电站的效率。 |

| Abstract： | In order to improve the dynamic accuracy of the speed regulation system for diesel engine in power station as well as to restrain load turbulence, the paper established and analyzed a mathematical model for diesel engine and its speed regulation system, thus an �H∞ controller for diesel engine speed regulation system in the power station is designed. By applying Matlab simulation calculation to the actual diesel engine speed regulation system in the power station, it is analyzed and found that when the outside environmental condition changes, i.e. when there is perturbation in system parameters, compared with other condition feedback control systems, the �H∞ controller designed in this thesis can effectively improve the dynamic accuracy and the turbulence-refraining ability of the diesel engine speed regulation system, thus the frequency stability of the ship power system is improved and efficiency of the ship power station is increased. |
