摘    要:摘要:结合滑模变结构控制和模糊逻辑技术,提出一种基于多目标优化的模糊滑模变结构控制。以滑模开关函数及其变化量作为模糊调节器的输入量,滑模面边界层的宽度作为输出量,设计一个二堆模糊边界层宽度调节器}以稳态误差和切换频率构造多目标优化函数,运用多目标优化算法对滑模变结构控制器参数进行优化。应用于液压位置系统控制的仿真结果表明,所提出的控制方法能缓解滑模变结构控制高稳态精度与平滑抖振之间的矛盾,提高液压位置滑模变结构控制系统的综合性能。

关 键 词:模糊滑模变结构控制  边界层调节  多目标优化  抖振削弱  稳态精度  液压位置系统

Abstract:Combining sliding mode variable structure control with fuzzy logic technique, a fuzzy sliding mode variable structure control based on multi-objective optimization was developed. A two-dimension fuzzy scheduling mechanism was designed for boundary width tuning due to the sliding mode plane function and its change rate. The overall objective function was formulated based on steady-state error and switching frequency. A multi-objective optimization algorithm was used to optimize the parameter of sliding mode variable structure control. The simulation results show that the design conflict between high steady-state precision and chattering reduction in the hydraulic servo sliding mode variable structure control system can be well balanced, and that good comprehensive performance can be obtained by using the proposed control.
Keywords:fuzzy sliding mode variable structure control  boundary tuning  multi-objective optimization  chattering reduction  steady-state precision  hydraulic positioning system
