| 摘要: |
| 针对一类不确定的非线性系统，把自适应模糊控制和积分滑模控制相结合，提出了一种新的自适应积分滑模模糊控制策略。利用模糊逻辑逼近系统中的未知非线性函数，在滑模控制中引入了积分项，消除了常规滑模控制器被跟踪信号导数已知的限制；并且为了消除外界扰动的影响，引入扰动估计器的设计方法；同时基于Lyapunov方法导出了参数的自适应律，有效地克服了系统固有的抖振问题。理论分析证明了闭环系统的稳定性和跟踪误差收敛于零。用该控制器对同步发电机混沌振荡控制系统进行仿真研究，结果表明：与常规的滑模控制器相比，该控制器具有较强的鲁棒性和较好的跟踪性能。 |

| Abstract: |
| An adaptive fuzzy integral sliding mode control scheme is proposed for a class of nonlinear systems，which approximates to the nonlinear function with fuzzy logic system，adds an integral item to the sliding mode control algorithm to avoid its assumption that the derivative of desired signal is known，adopts a disturbance compensator to eliminate the influence of system uncertainties，and applies the adaptive algorithm based on Lyapunov method to banish the chattering phenomenon inherent in sliding mode control. Theoretical analysis proves that the close loop system is stable and the tracking error converges to zero. Simulative results of synchronous generator chaos oscillation show that the control scheme has better robustness and tracking accuracy than traditional sliding mode controller. |
