动态滤波器 meaning in English

df damping factor
dynamic filter
kinetic filter

The main idea under controller design is damping model nonlmearities with control input to force the system dynamic into a linear sliding surface and utilizing dynamic filters to ensure the boundedness of states , inputs and outputs . the mismatched model uncertainties are suppressed with extra items in control input
Dsc控制器通过对消系统非线性项，将系统动态驱至线性滑模态；引入动态滤波器，确保系统的状态及输入输出有界，同时避免了对非线性模型多次求导带来的复杂性；在虚拟控制输入中利用附加项来克服不满足匹配条件的不确定性。
