摘要:
针对具有未知死区的电液比例系统,提出了一种带有死区补偿的变论域自适应模糊滑模控制方法。根据比例换向阀的死区特性,采用模糊逻辑系统设计死区预补偿器;将变论域的思想引入到自适应模糊滑模控制中,在线调节输入输出变量论域和隶属度函数,从而提高传统模糊滑模控制的精度;依据Lyapunov稳定性理论,构造变论域伸缩因子的自适应律,并对模糊逼近误差的上界进行实时估算,无需假设逼近误差上界已知。实验结果表明:采用变论域方法能有效地提高自适应模糊控制器的性能,在电液比例系统的位置跟踪控制中能克服系统固有的非线性特性、参数不确定性及外界干扰的影响,并且死区预补偿器消除了未知死区对跟踪精确度的影响,该方法具有响应快、精确度高、自适应鲁棒性强的特点。
Abstract:
Based on the thought of variable universe,a novel adaptive fuzzy sliding-mode controller with variable universe was proposed for electro-hydraulic proportional system with unknown dead-zone.Considering the property of proportional valve dead-zone,a dead-zone compensator was designed using adaptive fuzzy logic.In order to improve the control performance,the universe of input variable and the membership functions of conclusion part in rules were adjusted on-line.According to Lyapunov stability theory,scaling ...
