| Abstract: |
| The adaptive H∞ control problem of multi-machine power system in the case of disturbances and uncertain parameters is discussed, based on a Hamiltonian model. Considered the effect of time delay during control and transmission, a Hamilton model with control time delay is established. Lyapunov-Krasovskii function is selected, and a controller which makes the system asymptotically stable is got. The controller not only achieves the stability control for nonlinear systems with time delay, but also has the ability to suppress the external disturbances and adaptive ability to system parameter perturbation. The simulation results show the effect of the controller. |

| 考虑控制时滞的多机电力系统自适应鲁棒控制 吴忠强，李峰，杜春奇，张伟 （燕山大学 电气工程学院 河北省工业计算机控制工程重点实验室，河北 秦皇岛 066004） 创新点说明考虑多机电力系统控制传输过程中的时间滞后问题，建立了含控制时滞的Hamilton模型。同时考虑存在扰动和参数不确定的情况，设计出基于Hamilton模型的自适应H∞控制器。选择Lyapunov-Krasovskii函数分析了系统的渐近稳定性。该控制器不仅实现了对含有时滞的非线性系统的稳定控制，而且对外部扰动具有抑制能力，对系统参数摄动具有自适应能力。 关键词：多机电力系统；时滞；H∞控制；参数不确定；扰动 |
