摘要
在建立液压缸位置控制系统模型基础上,采用Matlab7.1进行了仿真和动态分析。研究了电液位置控制比例系统的动态特性。在分析传统PID及模糊控制器优缺点的基础上提出应用PI+模糊规则自校正的控制策略可改善其系统性能。仿真结果表明,PI+模糊规则自校正控制的电液位置控制比例系统控制效果较好。
Based on the modeling for position control system of the hydraulic cylinder, the dynamic analysis was made making use of the Matlab. The dynamic： performance of the electro-hydraulic proportional system of the position control was studied, the advantages and disadvantages of the conventional fuzzy controller were analyzed, a PI ＋ self-tuning fuzzy rules controller for a nonlinear proportional system was presented.
