A novel approach to stable zero dynamics of sampled-data models for nonlinear systems in backward triangle sample and hold case
作者：
Highlights：
• An approximate sampled-data model for nonlinear systems with backward triangle sample and hold function is first derived.
• Obtaining a novel expression and stable conditions of zero dynamics in the obtained sampled-data model.
• Zero dynamics of the resulting model can be arbitrarily placed by selecting proper parameters from the stable conditions.
• Nonlinear systems using those methods in this paper have better control performance.
