| 摘 要： | 传统自适应滑模需要系统扰动上界的先验信息和易引发作动器抖振是其不便用于工程实际的主要原因。文章基于扩张状态观测器对传统自适应滑模进行了改进,利用扩张状态观测器(ESO)实时观测外扰并在自适应滑模控制中进行补偿。将改进后的自适应滑模应用于舰载机俯仰姿态控制中,进行仿真计算。计算结果表明,在系统扰动上界未知的情况下,ESO提高了自适应滑模的鲁棒性,消除了抖振。

| Abstract: | The need of priori information of the disturbance upper bound and chattering are the main shortcomings of tradi? tional adaptive sliding mode control. Based on the extended states observer, the robust of the adaptive sliding mode control was improved and the chattering was eliminated without any priori information of the disturbance upper bound. The im? proved adaptive sliding mode control was applied to the attitude control system of a carrier-based aircraft. The simulation results shows the effectiveness of the improvement. |
