| 摘 要： | 针对多机电力系统励磁控制模型,考虑电力系统的状态不完全可测及多变量、非线性等特点,以T-S模糊逻辑系统直接逼近控制器,设计出基于状态观测器的直接自适应输出反馈模糊控制器,并通过李亚普诺夫函数进行了稳定性证明.算法具有很好的鲁棒性和动态性能,仿真结果表明所设计的控制器能够快速有效地改善系统在大干扰下的暂态稳定性.

| Abstract: | Based on multi-machine excitation control models whose states are not available, and with multi-input and multi-output,non-linearity,the T-S fuzzy logic systems being employed to direct approximate the controller,A kind of direct adaptive output feedback fuzzy controller is realized with the state observer.The stability is proofed through Lyapunov function. This algorithm has high robustness and dynamic performance.The simulation shows that the controller can effectively improve power system stability under big disturbance. |
