摘要
静液压传动系统具有高度非线性特性,且易受模型变化的影响。若使用工作点设计构成模糊控制器,将使控制器比较复杂,规则选择过程不直观,失去了模糊控制简单的优点。本文提出将自适应模糊逻辑控制应用于液压马达的转速控制,除设定的规则外,自适应模糊逻辑控制能根据液压马达转速的变化特性自动调整规则来适应马达转速特性变化所要求的控制规律。仿真实验结果显示,采用自适应模糊逻辑控制能改善马达的整个运行过程的速度特性。
Hydrostatic transmission system is highly nonlinear and subject to severe model variation. The fuzzy controller designed with the operating point is more complicated, the rule selection process is less intuitive. Self-adaptive fuzzy logic control was applied to the speed control of a hydraulic motor. The self-adaptive fuzzy logic control can automatically adjust the control rule according the speed change of motor. Simulated results show that self-adaptive fuzzy logic control can improve the speed performance of motor during the running.
