| 摘要: |
| 针对单机无穷大系统提出了一种解耦逆推自适应励磁滑模控制方法,以提高电力系统鲁棒稳定性.对于一类具有不确定性的半严格反馈形式的非线性系统,将构造李亚普诺夫(Lyapunov)函数的逆推设计方法和自适应机制以及滑模变结构控制有机结合,获得了一种保证该类系统全局渐近稳定的自适应滑模控制律以及自适应增益控制律.根据该设计结果,对含励磁控制的单机无穷大系统反馈线性化模型,得到了发电机的自适应滑模励磁控制器,仿真结果表明:该控制器能有效地稳定不确定电力系统,维持机端电压,具有比自适应逆推励磁控制器更好的性能. |

| Abstract: |
| A decoupled backstepping adaptive excitation control of sliding mode is presented for single-machine infinite - bus system to improve its robust stability. For the nonlinear systems with the semi - strict feedback form of uncertain parameters,the backstepping control design method is used to construct Lyapunov function,and the adaption control and sliding mode variable structure control are combined to achieve the adaptive sliding mode control and adaptive gain control,based on which,the adaptive generator ... |
