| 摘 要： | 分析了变结构控制设计方法中趋近律参数的物理意义及参数之间的定性关系 ,根据这些参数的定性和不精确关系 ,提出了基于模糊规则的趋近律控制——模糊趋近律控制 ,即用模糊规则来选择趋近律的参数 ,以达到改善品质控制的目的 .仿真结果表明 ,笔者给出的方法既保留了传统趋近律方法所具有的较强鲁棒性优点 ,又使控制系统的品质控制具有较强的自适应性 ,同时还比传统趋近律方法更有效地削弱变结构控制系统中固有的颤振 .

| Abstract: | The physical significances of the reaching law parameters and the qualitative relationships among them in variable structure control(VSC) are analyzed.According to the relationships,a reaching law control method is put forward based on fuzzy rules.To improve control quality,the reaching law parameters are selected by fuzzy rules.The control scheme presented in this paper not only preserves the advantages of traditional reaching law control,that is ,insensitivity to any variation and perturbation of the plant parameters,but also possesses the adaptation to control quality of variable structure control systems.The simulation results show the chattering in VSC systems is highly reduced. |
