摘要 本文针对数控系统轴控制中存在的非线性问题 ,从变结构理论的角度 ,应用边界层滑动控制理论设计了一个模糊滑动控制器 .滑动控制具有不依赖控制对象的精确数学模型的特性 ,适用于很多非线性控制问题 .另外 ,应用滑动控制理论也保证了所设计的模糊控制器的稳定性 . Aiming at the nonlinearity of machine tool axis, this paper presents the methodology of fuzzy slide mode controller based on slide mode control theory in the viewpoint of VSS. As the result of independence on the exact model of controlled plant, the slide mode controller is suitable for solving nonlinear problems, and can guarantee the stability of controller. The results of simulation on backlash verify the effect iveness of this methodology.
