| 摘要: |
| 早期的模糊控制器设计,主要依赖于专家经验,而且只是采用近似推理的方法。针对可控串补非线性系统,设计了一种直接自适应模糊控制器。建立模糊控制器逼近误差和控制器参数之间的线性关系,用Lyapunov稳定性理论设计参数的自适应律,不仅调节模糊规则结论参数,同时调节隶属函数的参数。将该控制策略应用于含可控串补电力系统中,提出可控串补自适应模糊阻尼控制器的设计方法。仿真表明该控制器对系统发电机摇摆具有良好的阻尼作用,提高了系统的稳定性。 |

| Abstract: |
| The earlier design of fuzzy controller is mostly based on experts' experience and only the approximate consequence method is adopted.Based on the nonlinear system of TCSC(Thyristor Controlled Series Capacitor),a direct self-adaptive fuzzy controller is designed.The linear relation-ship between the approach error and fuzzy controller parameters is established firstly.The parameter self-adaptive rule designed by Lyapunov stability theory adjusts both fuzzy rule conclusion parameters and membership function parameters.The control strategy is then applied in the power system with TCSC and a design method of TCSC self-adaptive fuzzy damping controller is provided.The simulation shows that the controller has good damping function to generator swing and the system stability is improved. |
