| 摘要: |
| 在介绍线性最优控制理论的基础上，主要基于SIMULINK交互式仿真集成环境对三阶发电机实用模型的励磁系统进行LOC仿真研究，可视化比较了励磁系统最优控制前后的系统输出波形差异，突出指明最优反馈矩阵K的取值对权矩阵Q大范围变动的不敏感性，同时阐释了在设计运行点所获得的固定线性最优控制规律在发电机通常运行范围内的工况自适应性，即采用固定增益在较大运行范围内都可以得到接近最优的动态特性。 |

| Abstract: |
| Based on the theory of Linear Optimal Control(LOC),the LOC simulation of the 3 order dynamo excitation system on SIMULINK is analyzed and the output wave differences between with and without LOC control are illustrated.It is specially pointed out that the optimal feedback array K has a thick skin of the power array Q variations.It is also indicated that the fixed optimal feedback control law obtained at the designed operating point has mode adaption around the usual operation range,viz.the dynamic quality approaching optimum can be assured in a biggish operating area. |
