    摘要:

    针对采用直行程气缸控制的阀门设计了智能阀门定位器。为研究其控制方法,采用AMESim/Simulink联合仿真,在AMESim中建立气动伺服阀控非对称缸的系统模型,以S 函数的形式导入到模糊自整定增量式PID控制系统的Simulink模块中,得到气动伺服系统的响应特性。将有、无PID系统的响应特性进行对比分析, 结果表明:模糊自整定增量式PID控制器可以改善气动伺服系统的响应性能,达到了调节精度高、调节速度快的目的。

    Abstract:

    In view of the straight travel cylinder controlled valve, the intelligent valve positioner was designed.To study the control algorithm of valve positioner,which was a nonlinear, time varying and unknown model system, asymmetric cylinder pneumatic servo system model was established by using AMESim, which was imported into the corresponding incremental fuzzy selftuning PID control system Simulink model in the form of S function to study models responses of the pneumatic servo system. Comparing two kinds of response characteristics,the results show that the fuzzy selftuning incremental PID controller can improve the response performance of the pneumatic servo system and achieve the goal of the high precision and high speed in the adjustment process.
