摘要
分析了项目改造中钢管水压试验机的工作原理。在控制系统改造过程中,根据实际工业过程对鲁棒性的要求,利用模糊控制不需系统精确数学模型且具有较强鲁棒性等优势,改进了PID控制对液压非线性系统控制的一些不足,在实际生产中取得了较好效果。同时,简要介绍了模糊控制中常用的二输入单输出的设计思想及方法。
Analyzes the working principle of large steel pipe hydraulic test machine in the changes of project. According to the robustness requirement of the practical work process, takes the advantages of fuzzy control to improve the PID control on the non-linear hydraulic servo system, which doesn＇t need accurate mathematics model of control object and has good robust, and achieves good effect in production. Meanwhile introduces the design idea and method for two-input and one-output fuzzy control system.
