针对非匹配干扰的衰减，提出了一种连续非奇异终端滑模控制方法。设计了一种基于有限时间扰动观测器的非线性动态滑模曲面。在不匹配扰动下，从任意初始状态到达期望的设定值所花费的时间保证是有限的。此外，该方法还具有良好的名义性能恢复和颤振缓解性能。
A continuous nonsingular terminal sliding mode control approach is proposed for mismatched disturbance attenuation. A novel nonlinear dynamic sliding mode surface is designed based on a finite-time disturbance observer. The time taken to reach the desired setpoint from any initial states under mismatched disturbance is guaranteed to be finite time. In addition, the proposed method exhibits the fine properties of nominal performance recovery as well as chattering alleviation.
