摘要
基于液压伺服系统参数不确定性,提出一种改进的模型参考自适应模糊控制方法。该方法用模糊自适应机构代替常规的自适应机构,并用模糊因子自调整律实时调节模糊自适应机构的模糊规则。此方法提高了模糊自适应机构推理规则的调整精度,获得了更好的控制性能。仿真结果验证了该方法的优越性。
Since the uncertainty of parameter of hydraulic servo system, an improved model reference adaptive fuzzy control was proposed. The solution use fuzzy adaptive mechanism instead of traditional adaptive mechanism, and can dynamically adjust the rules of fuzzy adaptive mechanism by fuzzy factor auto-adjusting. It improves the adjusting precision of fuzzy adaptive mechanism, and obtains better controlling quality. The simulating results demonstrate the effectiveness of this approach.
