| 摘 要： | 提出一种基于边界层模糊调节的准滑模变结构控制方法.基于滑模开关函数及其变化量,设计一个二维边界层模糊调节器,根据滑模开关平面状态的变化动态调整滑模边界层的宽度.应用于液压位置系统的控制实验结果表明,所提出的控制方法能保证液压系统响应速度,提高控制精度,削弱抖振,较好地协调了变结构控制鲁棒性与平滑控制抖振之间的矛盾. |
| 关 键 词： | 准滑模变结构控制 边界层 模糊调节 抖振削弱 稳态性能 液压位置系统 |

| Abstract: | A quasi-sliding mode variable structure control(QSMVSC) based on fuzzy scheduling boundary was developed and applied to the positioning control of a hydraulic servo system.A two-dimension fuzzy scheduling mechanism was designed. The boundary width of sliding mode plane was dynamically tuned due to the sliding mode plane function and its change rate.Experiment results applied to the hydraulic positioning system showed that fast response,higher precision,and chattering reduction could be carried out by using the proposed QSMVSC based on fuzzy scheduling boundary,as well as the conflict between the robustness and control smoothing in the hydraulic positioning system were balanced. |
| Keywords: | quasi-sliding mode variable structure control(QSMVSC) boundary layer fuzzy scheduling chattering reduction steady-state characteristics hydraulic positioning system(HPS) |
