摘要
提出一种抑制抖振的新方法。此方法把引起抖振的因素归纳为系统数学模型的不确定性，并采用Ｈ∞优化方法设计滑模变结构控制的切换面。由于它能使滑动模态实现希望的频率整形，故能有效地抑制抖振。计算机仿真实验结果证实文中所提出的方法是有效的。
A new method of reducing chattering in sliding mode control is proposed,which considering the chattering as the results of uncertainty in the system mathematic model and using H ∞ optimization design of switching surface.Frequency shaping of sliding mode can be achieved and chattering can be reduced well via the method.The effectiveness of the proposed method is verified by the results of digital simulation.
